1) Water is stored in a large storage tank at 30.0°C open to atmosphere (Tank 1). It is pumped at a rate of 50 m'/h to another pressurized tank (Tank 2) at 21.0°C and 32 m above, as shown below. The pipeline used is 5 cm in diameter commercial steel with a total length of 80 m. The water passes through a heat exchanger where 50 kW of heat is removed from the water. The flow system consists of two 90° elbow and 1 wide open gate valve. Calculate the power that should be supplied by the pump in kW (Water properties at 21.0°C can be used to calculate the Reynolds number in the flow system).
