Answer:
at constant pressure, the heat flow for any process is equal to the change in the internal energy of the system plus the PV work done. Comparing the previous two equations shows that at constant pressure, the change in the enthalpy of a system is equal to the heat flow: ΔH=qp.

Answer:
The ACH is 12/h
Solution:
As per the question:
Area of the space, 
Height of the given space, h = 10 ft
Air flow rate, 
Now, to find the Air Change Rate (ACH):
We calculate the Volume of the given space:
Now, the ACH per min:
= 
Now, ACH per hour:
= 
Answer: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended
