2) The pump of a water distribution system is powered by an electric motor whose efficiency is 80% with a shaft that is 97% efficient and a pump that is 60% efficient. The water flow rate through the pump is 0.2 m³/s. What is the total efficiency of the pump/motor assembly? The diameters of the inlet and outlet pipes are the same, and the elevation difference across the pump is negligible. If the pressures at the inlet and outlet of the pump are measured to be 70 kPa and 720 kPa (absolute), respectively, determine the electrical consumption of the pump.

Check Your Understanding If the reservoir in Example 14.1 covered twice the area, but was kept to the same depth, would the dam need to be redesigned?

Water supplied to a house by a water main has a pressure of 3.00105N/m2 early on a summer day when neighborhood use is low. This pressure produces a flow of 20.0 L/min through a garden hose. Later in the day, pressure at the exit of the water main and entrance to the house drops, and a flow of only 8.00 L/min is obtained through the same hose. (a) What pressure is now being supplied to the house, assuming resistance is constant? (b) By what factor did the flow rate be water main increase in order to cause this decrease in delivered pressure? The pressure at the entrance of the water main is 5.00105N/m2 , and the original rate was 200 L/min. (c) How many more users are there, assuming each would consume 20.0 L/min in be morning?

1) A compressor is delivering air at a pressure of 8 bar gauge at the rate of 10 m3/min f.g.d. Average circuit demand is 4 m³/min. of free air, at a minimum pressure of 6 bar gauge. What must be the size of the receiver tank such that no of start/stops do not exceed 20 every hour ?

A certain fluid at 10 bar is contained in a cylinder behind a piston, the initial volume being 0.05 m3. Calculate the work done by the fluid when it expands reversibly, (a) At constant pressure to final volume of 0.2 m3 ; (b) According to linear law to final volume of 0.2 m3 and a final pressure of 2 bar (c) According to a law pV= constant to a final volume of 0.1 m3 ;  (d) According to law pV3 = constant to a final volume of 0.06 m3. Sketch all processes on p-V diagram.

4 A sample A of liquid water and a sample B of ice, of identical mass, are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure 18-25a is a sketch of the tempera- ture T of the samples versus time t. (a) Is the equilibrium temperature above, below, or at the freezing point of water? (b) In reaching equi- librium, does the liquid partly freeze, fully freeze, or undergo no freez- ing? (c) Does the ice partly melt, fully melt, or undergo no melting?

Is the specific speed of the pump ideal or not?
