If the digital inputs for a supply-air fan control application show that the supply-air fan should be ON, the controller compares the measured static air pressure to the set point.
The operation of a supply-air fan control.Basically, the controller of a supply-air fan control application is designed and developed to compare the measured static air pressure to the set point when its digital inputs indicate that the supply-air fan should be ON.
By design and configuration, if the measurement of the static air pressure is lower than the set point, the supply-air fan speed must be increased by an engineer accordingly.

Conductors in Parallel is covered in 310.10(H). Often when working with higher ampacities, we find it to be cumbersome and expensive to keep increasing the size of the wire and conduit. The solution is often to use multiple runs that are connected to a common location on each end. Notice in the 2011 edition of the code that much of this section is highlighted gray, indicating new or revised text. The change here was that the previous code stated that you were permitted to parallel conductors 1/0 AWG and larger; however, it didn’t specifically prohibit you from paralleling smaller conductors, which was the intent and the way it was enforced in all my years of enforcement. However, that’s not what the actual language said, and ambiguous language cancause enforcement issues; therefore, in the 2011 code it was made clear that you are only allowed to parallel conductors 1/0 AWG and larger.
The velocity of the water jet discharging from the orifice can be obtained from v=\12ih, where h = 2 m is the depth of the orifice from the water surface. Determine the time for a particle of water leaving the orifice to reach point B and the horizontal distance x where it hits from surface.
The time for a particle of water leaving this orifice to reach point B and the horizontal distance are 0.553 seconds and 3.46 meters respectively.
How to calculate the time?First of all, we would determine the velocity of the water jet discharging from the orifice by using this formula:
V = √(2gh)
V = √(2 × 9.81 × 2)
V = 6.264 m/s.
Next, we would determine the time taken to reach point B as follows:
S = Sa + Uy(t) + ½at²
-1.5 = 0 + 0(t) + ½ × (-9.81) × t²
t = 0.553 seconds.
Now, we can determine the horizontal distance:
x = xa + Vt
x = 0 + 6.264(0.553)
x = 3.46 meters.

A transformer has 300,000 windings in its primary coil and uses 12,000V AC input. (4 points) How many windings would be needed to produce at output of 110V AC
Answer:
2750
Explanation:
The number of windings and the voltage are proportional.
__
Let n represent the number of windings to produce 110 Vac. Then the proportion is ...
n/110 = 300,000/12,000
n = 110(300/12) = 2750 . . . . multiply by 110
2750 windings would be needed to produce 110 Vac at the output.

C) recovers refrigerant in a non-pressurized container. D) can only be performed on a system with an operating compressor.
Answer:
C) recovers refrigerant in a non-pressurized container
The system dependent (passive) recovery process recovers refrigerant in a non-pressurized container. The correct option is C.
A way of recovering refrigerant from a system without using a pump or heat is known as a system-dependent (passive) recovery process.
Instead, it relies on the system's normal pressure and temperature variations to speed up the recovery process.
A non-pressurized container is commonly connected to the system using this technique, and the refrigerant is then passively allowed to flow inside the container.
The system-dependent recovery procedure, according to Option C, recovers refrigerant in a non-pressurized container.
