A pump is used to take water out of a large lake and deliver it to a farm to be used for irrigation. The pump location is illustrated in Figure 3.42, where the suction side of the pump (also called the pump intake) is 3.5 m above the water surface in the lake and the vertical intake pipe has a diameter of 130 mm. Assuming that viscous effects are negligible, what is the pressure on the suction side of the pump when the flow rate through the system is 120 L/s?
