Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

8.. An air blower is to deliver 40,000 ft3 /min. Two U-tube gages measure suction and discharge pressures. The suction gage reads a negative 2′′ of water. The discharge gage, located 3 ft above the point to which the suction gage is attached, reads +3′′ of water. The discharge and suction ducts are of equal diameter. What size motor should be used to drive the blower if the overall efficiency is 68% (γ = 0.0750 lb/ft3 for air)? indicate free body diagram
