In an open-top large storage tank (Tank 1), hot water at 93.3°C is being pumped into another open-top large tank (Tank 2) at a mass flow rate of 1.5 kg/s. The pipeline consists of a 1-inch Schedule 40 commercial steel pipe with a length of 325 m and includes 5 elbows (90°), 2 U-turns, 1 semi-open sliding valve, and 50 connection elements. The water level in Tank 2 is 22 m above the water level in Tank 1. a) If the pump efficiency is 60%, calculate the power of the pump in kW. b) Calculate the pressure difference created by the pump. c) If the electric motor connected to the pump has an efficiency of 88%, can you comment on how many kW of electricity this system consumes?"

Answer rating: 100% (QA)

SOLUTION a To calculate the power of the pump we need to determine the heat transfer rate from Tank 1 to Tank 2 This can be calculated using the following equation Q m Cp T where Q is the heat transfe... View the full answer
