a six pulse scr controlled rectifier is supplied with 13.8 kv from a 1 mva transformer. the transformer is connected wye-wye and its reactance is 10%. the transformer secondary is rated 6000 v. the rectifier load is 900 kw (dc) at 7600 v. estimate the supply current component at 300 hz on the transformer high side.
The supply current component at 300 Hz on the transformer high side is 0.0591A.
What is transformer?
A transformer is indeed a passive part that moves electrical energy between circuits, whether they be single circuits or multiple circuits. The electromotive force (EMF) across all other coils pierced around the same core changes in response to changes in the current flowing through any one of the transformer's coils, which causes changes in the magnetic flux with in transformer's core. Without a metallic (conductive) connecting the two circuits, electrical energy can be transmitted between different coils. The 1831 discovery of Faraday's law of induction defines the voltages effect in any coil as the result of a fluctuating magnetic flux surrounding the coil.
The supply current component at 300 Hz on the transformer high side can be estimated as follows:
1. Calculate the total current drawn by the rectifier load:
The total current drawn by the rectifier load is calculated as follows:
Iload = Pload/Vdc = 900kW/7600V = 118.18 A
2. Calculate the total transformer secondary current:
The total transformer secondary current is calculated as follows:|
Isec = Iload/KVA = 118.18A/1MVA = 0.11818 A
3. Calculate the transformer primary current:
The transformer primary current is calculated as follows:
Ipri = Isec * (Vpri/Vsec) * (1 + X/100) = 0.11818A * (13.8kV/6kV) * (1 + 10/100) = 0.3545 A
4. Calculate the supply current component at 300 Hz on the transformer high side:
The supply current component at 300 Hz on the transformer high side is calculated as follows:
Isupply = Ipri/6 = 0.3545A/6 = 0.0591 A
Therefore, the supply current component at 300 Hz on the transformer high side is 0.0591A.

water flows at a rate of 0.9 m3/s in a 2.5 m wide channel as shown. at a particular section, the flow depth is 1.2 m. a. what would be the flow depth over a bump of height 0.1 m installed just downstream of this section? b. what is the maximum elevation of the bump that could be installed without backing/ choking the flow (hint: look for ec in y-e diagram)
The depths immediately upstream and downstream of the lowered segment, or normal depth, are those in the approach flow.
The amount of water that might theoretically flow out of your kitchen faucet or bathtub each minute is measured by your water flow rate, sometimes referred to as your gallons per minute (GPM).
Assuming your flow rate is currently standard, your home will never need to exceed that final GPM unless you intend to build more kitchens, bathrooms, or laundry rooms. The typical residential water flow rate for small homes is between 6 and 12 gallons per minute.
Add the average breadth (in m), the average depth (in m), and the average water velocity (in m/s) together to get the water flow (in m3) (in m). Water flow equals 0.255 m3/s (0.425 m/s x 1 m x 0.6 m).

A dislocation formed by adding an extra half-plane of atoms to a crystal is referred to as a Shockley partial dislocation.
Understanding Shockley Partial DislocationsA Shockley partial dislocation is a type of dislocation that occurs when an extra half-plane of atoms is added to a crystal. It is a misfit dislocation, meaning that the extra plane does not fit into the lattice of the crystal.
This can cause strain and stress to build up in the crystal, leading to defects and other issues in the crystal structure. The Shockley partial dislocation can cause the atoms in the crystal lattice to become misaligned, resulting in a weakened structure. In order to reduce the strain and stress that this type of dislocation causes, the atoms in the extra plane must be removed or replaced with new atoms that fit into the lattice. This can help to restore the crystal to its original, undamaged state.

The router will then forward all four fragments to the link with an MTU of 1500 bytes.
What is router?
Among computer networks, a router is a network device that forwards information packets. Between networks and across the global Internet, routers handle traffic directing. Data sent over a network, like an email or a web page, is sent in the form of data packets. In order to reach its destination node, a packet has been typically forwarded through one router to some other router thru the networks that make up an internetwork (such as the Internet). A number of data cables from separate Ip networks are connected to a router. The router gets to read the network address details from the packet header when a data packet arrives on one of the lines to ascertain the final destination.
The router must fragment the datagram into four fragments of 1500 bytes each. The IP header will be split across all four fragments, so each fragment will have an IP header of 20 bytes and a payload of 1480 bytes. The first fragment will have the More Fragments bit set to 1, and the other three fragments will have it set to 0 to indicate that they are the last fragments. The router will then forward all four fragments to the link with an MTU of 1500 bytes.

A country needs to build new power plants to meet
the increasing demand for electric power. One possibility is
to build coal-fired power plants, which cost $1300 per kW
to construct and have an efficiency of 40 percent. Another
possibility is to build clean-burning Integrated Gasification
Combined Cycle (IGCC) plants where the coal is subjected to
heat and pressure to gasify it while removing sulfur and particulate matter from it. The gaseous coal is then burned in a
gas turbine, and part of the waste heat from the exhaust gases
is recovered to generate steam for the steam turbine. The construction of IGCC plants costs about $1500 per kW, but their
efficiency is about 48 percent. The average heating value of
the coal is about 28,000,000 kJ per ton (that is, 28,000,000 kJ
of heat is released when 1 ton of coal is burned). If the IGCC
plant is to recover its cost difference from fuel savings in five
years, determine what the price of coal should be in $ per ton.
Answer:
To determine the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years, we first need to calculate the cost savings of the IGCC plant compared to the coal-fired power plant. The IGCC plant costs $1500 per kW to construct and has an efficiency of 48 percent, while the coal-fired power plant costs $1300 per kW to construct and has an efficiency of 40 percent. The cost savings of the IGCC plant can be calculated as follows:
$1500/kW - $1300/kW = $200/kW
We can then calculate the total cost savings of the IGCC plant over a five-year period by multiplying the cost savings per kW by the total number of kW the plant will generate in five years. For this calculation, we will assume that the plant will generate 1,000 kW of power.
$200/kW * 1000 kW = $200000
Next, we need to calculate the amount of coal that the IGCC plant would need to burn over a five-year period to generate 1,000 kW of power. We know that the average heating value of coal is 28,000,000 kJ per ton, and that the efficiency of the IGCC plant is 48 percent. We can calculate the amount of coal the IGCC plant would need to burn as follows:
1,000 kW / (28,000,000 kJ/ton * 0.48) = 10.7 tons
Finally, we can calculate the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years by dividing the total cost savings by the amount of coal the plant would need to burn over the same period.
$200000 / 10.7 tons = $18,661.04/ton
Therefore, the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years is $18,661.04/ton.

Technician B is correct. DC current is used to power hybrid drive electric motors.
The Importance of DC Current in Hybrid Drive Electric MotorsThe modern world is becoming increasingly reliant on electric motors to power a range of different machines and vehicles. Hybrid drive electric motors are a key component of this technology, as they combine the power of an internal combustion engine with the efficiency of an electric motor. These motors are powered by direct current (DC) instead of the alternating current (AC) used in most chassis circuits. In this essay, we will discuss the importance of DC current in hybrid drive electric motors, why it is preferred over AC current, and the advantages that DC current provides in these motors.
The primary reason why DC current is used in hybrid drive electric motors is because it is more efficient than AC current. DC current is able to provide a constant level of power, whereas AC current can fluctuate depending on the voltage. This constant level of power is important for hybrid drive electric motors, as it ensures that the motor can consistently produce the power necessary for its intended application. Furthermore, DC current is able to transfer power more efficiently than AC current, meaning that the motor can use less energy to produce the same amount of power.

the motor in a refrigerator has a power of 200 w. if the freezing compartment is at 270 k and the outside air is at 300 k, and assuming the efficiency of a carnot refrigerator, what is the maximum amount of energy that can be extracted as heat from the freezing compartment in 10.0 min?
The maximum amount of energy that can be extracted as heat from the freezing compartment in 10.0 min is 1.08×10^6J.
Define energy engineering.
Engineering or Systems for Energy Energy efficiency, energy services, facility management, plant engineering, environmental compliance, sustainable energy, and renewable energy technologies all fall under the broad umbrella of engineering. To work as an energy engineer, one must possess a bachelor's degree in engineering.
A bachelor's degree is a terrific place to start, but certain jobs could want further training or qualifications. For students to develop their skills and knowledge further, additional training or internships are advised. For reducing energy use and consumption, these engineers create solutions. Green solutions are implemented, reducing costs and environmental effects through study, design, documentation, and implementation.
Solution Explained:
Work done by the motor in time (t)=10.0min
∣W∣=Pt=(200W)(10.0min)(60s/min)
∣W∣=1.20×10^5J
Heat extracted is then is
[tex]|Q_{L}| = K |W| = \frac{T_L |W|}{T_H - T_L} = \frac{(270K) (1.20 X 10^5)}{300K - 270K} = 1.08 X 10^6J[/tex]

A small sphere with charge -2.00 uC is located at x = 0, y = 5.00 cm. What is the magnitude of the force that the charged sphere exerts on the line of charge? Express your answer with the appropriate units. = uÅ ? F = 1.8. 10-3 IN Z Submit Previous Answers Request Answer
The charged sphere pushes against the line of charge with a force of 0.0181 N.
What is force between the charges' magnitude?The product of the magnitudes of the charges and the square of the distance between them determines the magnitude of the electrostatic force F between two point charges, q1 and q2, and vice versa. While opposing charges attract one another, like charges repel one another.
Apply the electrostatic force law of Coulomb.
F = (kq1q2)/r²
where;
Charge is q1. 1.26 nC = 6.3 n C/m x 0.2 m
F = (9 x 109 x 1.26 x 109 x 4 x 106)/q2
= charge 2 = -4 C
r = distance between the charges = 5 cm
= 0.05 m (0.05)²
F = 0.0181 N

a. true
b. false
The statement "the enormous gains in crop yields brought about by green revolution technologies may soon stop" is definitely true.
What is the Green revolution?The green revolution may be defined as a type of revolution in which there would be a great increase in the production of food grains (such as rice and wheat) due to the introduction of high-yielding varieties, the use of pesticides, and better management techniques.
It started around the 1960s and helped in increasing food production in the country. The green revolution's primary aim was to introduce high-yielding varieties (HYVs) of cereals to alleviate poverty and malnutrition. They soon stop because they are not much efficient as pear present needs and conditions.
