In a pump that works with cold water, the discharge pressure gauge located 7.5 m above the axis of the pump marks a pressure height of 68 m.c.a. The vacuum gauge located 125 cm below the axis of the pump shows a relative pressure of 325 Torr. Due to the difference in diameters between the suction pipes The momentum is created a dynamic height of ½ m. Calculate the useful head of the pump?
