Question

Water at 21°C and atmospheric pressure in a large tank is desired to be used as cooling water for a process which is then discharged to a large lake on a hill as shown in the figure.

a) Calculate the heat gained by the water if the final temperature of the water discharged to the lake is 26 °C. The pump used in the process delivers energy at a rate of 8.5 kW with the volumetric flow rate of 40 m3 /h.
b) Calculate the pressure developed by the pump if the suction line is a 3-in Schedule 40 pipe and discharge line is a 2-in Schedule 40 pipe.

The process is at steady state and it can be assumed that there are no energy losses throughout the process.
