In time-temperature defrost controls, the temperature that actuates the control is the temperature of the _____ _____.

Answers

In time-temperature defrost controls, the temperature that actuates the control is the temperature of the evaporator coil. These controls combine both time and temperature parameters to initiate the defrost cycle, ensuring efficient operation of the refrigeration system.

In time-temperature defrost controls, the temperature that actuates the control is the temperature of the evaporator coil. Time-temperature defrost controls are commonly used in refrigeration systems to prevent frost buildup on the evaporator coil. When frost accumulates on the evaporator coil, it reduces the efficiency of the refrigeration system and can even cause damage to the compressor.

To prevent frost buildup, time-temperature defrost controls use a combination of time and temperature measurements. The control is set to activate at a certain time interval (usually several hours) and also monitors the temperature of the evaporator coil. When the temperature reaches a certain threshold (typically around 32°F), the control initiates a defrost cycle.

During the defrost cycle, the evaporator coil is heated to melt the accumulated frost. The length of the defrost cycle is determined by the control based on the amount of frost present and the time elapsed since the last defrost cycle. Once the defrost cycle is complete, the control returns to monitoring the temperature of the evaporator coil and resumes its time-based defrost cycle.

Overall, time-temperature defrost controls are an important part of refrigeration systems that help maintain efficiency and prevent damage to the compressor. By monitoring the temperature of the evaporator coil and initiating defrost cycles as needed, these controls help ensure optimal performance of refrigeration systems over time.

Answers

The angle of attack of a wing directly controls the C) distribution of pressures acting on the wing.

When the angle of attack of a wing is increased, the air moving over the curved upper surface of the wing must travel a greater distance and faster than the air moving beneath the wing's flat lower surface. This creates an area of lower air pressure above the wing and an area of higher air pressure beneath the wing, resulting in lift. The greater the angle of attack, the greater the lift produced.

However, if the angle of attack is too great, the airflow over the wing may separate, causing a loss of lift and potentially leading to a stall. Therefore, proper control of the angle of attack is crucial for safe and efficient flight.

If the airspeed is increased from 89 knots to 98 knots during a coordinated level 45 degree banked turn, the load factor will decrease and the radius of turn will increase.

This is because increasing the airspeed during a turn reduces the amount of lift generated by the wings, which causes the load factor to decrease. Additionally, as the aircraft's speed increases, it needs to maintain a larger radius of turn to prevent stalling or losing control.However, increasing the airspeed will cause the aircraft to cover more ground in the same amount of time, which means that the radius of turn will increase in order to maintain the same rate of turn. This is because the lift required to maintain a constant turn is proportional to the square of the airspeed and inversely proportional to the radius of turn.

Imagine that the Sun could be turned into a black hole without changing its mass. How would Earth's orbit change?Choose matching definitionEarth would be flung off into outer space.Both a and b are possible.Part of a binary system.Earth's orbit would not change

Answers

Earth's orbit would not change if the Sun were turned into a black hole without changing its mass.

The mass of the black hole would be the same as the mass of the original Sun, so the gravitational force it exerts on Earth would be the same. The only difference would be that the distance from Earth to the black hole's event horizon would be smaller than the distance from Earth to the Sun's surface, due to the smaller size of the black hole. However, this difference would be negligible for Earth's orbit, which is much larger than the size of the event horizon. Therefore, option D ("Earth's orbit would not change") is the correct choice.

Question 78 Marks: 1 A special engineering study is required for slopes with an incline greater thanChoose one answer. a. 8 percent b. 6 degrees c. 8 degrees d. 4 percent

Answers

The correct answer is (b) 6 degrees. A special engineering study is required for slopes with an incline greater than 6 degrees, as stated in the International Building Code (IBC) section 1612.3.

In civil engineering and construction, a slope refers to an inclined surface or ground. Slopes can be found in a variety of natural and man-made environments, including hillsides, road embankments, building sites, and retaining walls. The slope of a surface is typically measured in terms of its angle of inclination or its gradient. The angle of inclination is expressed in degrees, while the gradient is expressed as a percentage or a ratio. For example, a slope with a 10% gradient rises 10 units for every 100 units of horizontal distance. Slopes can pose various challenges and hazards, including erosion, landslides, and instability. For this reason, proper design and construction techniques are necessary to ensure the safety and stability of slopes, especially those located near buildings, roads, or other infrastructure. Special engineering studies may be required for slopes with steep inclines or other potentially hazardous conditions. These studies typically involve detailed analysis and testing to evaluate factors such as soil composition, water content, and stability, and to determine appropriate design measures and safety precautions.
