6.JA U-tube manometer is connected to a closed tank containing air and water as shown in
the following figure. At the closed end of the manometer the air pressure is 16psia.
Determine the reading on the pressure gage for a differential reading of 4ft on the
manometer. Express your answer in psi (gage). Assume standard atmospheric pressure, and
neglect the weight of the air columns in the manometer.
