Water at 5°C is to be pumped from the river to the bottom of a water tower. The pump is 5 m above the river (dimension "a" on the diagram below) and is supplied by a 6.00 inch schedule 40 pipe. The tank is 19.5 m above the pump (dimension "b" on the diagram below) and is supplied by a 4 inch schedule 40 pipe. The water level in the tank is 4.3 m above the inlet (dimension "c" on the diagram below). The pump delivers 0.021 m/s. Losses are estimated to be 1.2 m between the river and the pump, and 4.2 m between the pump and the tank. Discharge line Suction line Pump River a) Calculate the losses in the suction line in kPa, based on the given head loss in m. kPa b) Calculate velocity in the suction line in m/s. m/s c) What is the pressure at the inlet to the pump in kPa? kPa
