A pump is pumping water at a flow rate of 1200 litres per minute. In the pump the mechanical energy of the water increases by 250 J/kg. The density of water is 1000 kg/m3. a) Determine the pressure difference between the pump outlet and the pump inlet. Assumptions: there are no frictional losses in the pump, and differences in velocity and elevation between inlet and outlet of the pump can be neglected. b) Show that the mechanical power added to...

A refrigeration plant chills water and delivers it to a heat exchanger some distance away, as shown in Fig. 9-17. The supply water temperature is ti°C, and the return water temperature is t2. The flow rate is w kg/s, and the pipe diameter is D m. The cooling duty at the heat exchanger is 1200 kW, and the arithmetic mean temperature, (fi 2)/2, must be 12°C in order to transfer the 1200 kW from the air. The pump develops a...
