1. A process liquid is transported through a 3 cm inside diameter pipe at a rate of 7.5 kg/min. Given the density of the liquid is 750 kg/m', calculate the change in kinetic energy for this stream in joules per second (5 marks) 2. Water supply for a remote area is obtain from a lake on a nearby hill. The surface of the lake is 120 m above the residential area and water is received at a flow rate of 12.0 kg/s. Given the density of water is 1000 kg/m?, calculate the rate of change in potential energy (5 marks]
