Water at 60 ∘C is pressurized in a pump from 90 kPa to 1600 kPa. If this requires 2.4 kJ for every kg of water that moves through the pump, then what is the isentropic efficiency of the pump? (Assume the mechanical efficiency is 100%)

Expert Solution

To find the isentropic efficiency of the pump, we will take ratio of isentropic work input and actual work input (2.4 KJ/kg).

To find the isentropic work input, we will have to use compressed water table. I have used the ones provided by NIST.

A pump takes water at 60°F from a large reservoir and delivers it to the bottom of an open elevated tank 25 ft above the reservoir surface through a 3 inch ID pipe. The inlet to the pump is located 10 ft below the water surface, and the water level in the tank is constant at 160 ft above the reservoir surface. The pump delivers 150 gpm. If the total loss of energy due to friction in the piping system...

Example 3.7: A commercial steel piping system is delivering water at 30°C from pressurized tank A to pressurised tank B as shown in figure below. The internal diameter of the pipe is 2.25 cm. The piping system has a well rounded inlet, 1/4 open gate valve, four 90° flanged bend, two 90° miter bend (with vane) and a sharp exit. The total pipe length is 300 m. Gauge pressure at tank A is 500 bar. If the elevation difference, h...

A small water pump is used for an irrigation project. The pump takes water in from a river at 10oC, 100 kPa at a mass flow rate of 16.83 kg/s. The exit line enters a pipe that goes up to an elevation 26.15 mm above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 10 oC. Find the required pump work.

A centrifugal pump is to be used to pump water from a lake to a storage tank which is 165 feet above the surface of the lake. The pumping rate is to be 10 - 35 gal/min at a water temperature of 43°F. The water is used for drinking but will have to undergo filtration and chlorine treatment because there is sediment in the lake. The pump on hand can develop a discharge pressure of 60.0 psig pumping at a...

An isentropic pump compresses water between the pressures listed in Problem 1 (30 & 8000 kPa) at the same mass flow rate (3 kg/s). Assuming saturated liquid conditions at the inlet of the pump, determine: a) The power required to operate the pump b) The ratio of the turbine power output from problem 1 to the required power input of the pump
