Extracted text: 9. Hot water in an open storage tank at 82.2°C is being pumped at the rate of 0.379 m³/min from this storage tank. The line from the storage tank to the pump suction is 6.1 m of 2-in. Schedule 40 steel pipe and it contains three elbows. The discharge line after the pump is 61 m of 2-in. pipe and contains two elbows. Water discharges to the atmosphere at a height of 6.1 m above the water level in the storage tank. a. Calculate all frictional losses EF. b. Make a mechanical-energy balance and calculate of the pump in J/kg. s W c. What is the kW power of the pump if its efficiency is 75%?
