7.14 The pump in Fig. 7.20 delivers water from the lower to the upper reservoir at the rate of 0.057 m3/s. The energy loss between the suction pipe inlet and the pump is 1.83 m and that between the pump outlet and the upper reservoir is 3.66 m. Both pipes are 6-in Schedule 40 steel pipe. Calculate (a) the pressure at the pump inlet, (b) the pressure at the pump outlet, (c) the total head on the pump, and (d)...

A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree C through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet temperature is raised to 40 degree C?

A centrifugal pump is pumping water at a rate of 35.55 gal/min. The pressures at the inlet, and outlet of the pumps are -2.26 psig and 7.715 psig respectively. The outlet pipe is placed 10 inches higher than the inlet pipe. The inlet and outlet diameters of the pipe are 1.85 in and 1.6 in respectively and the torque produced by the pump rotating at 1593 rpm is 3.172 ft.Ibf. Calculate the following in SI units: a) Total head b)...

(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...
