Include a free body diagram. A 12′′ pipe is being tested to evaluate the lost head. When the flow of water is 6.31 cfs, the pressure at point A in the pipe is 40 psi. A differential gage is attached to the pipe at A and at a point Bdownstream that is 10 ft higher than A. The deflection of mercury in the gage is 3.33 ft, indicating a greater pressure at A. What is the lost head A to 5?
