Cooling water available at 10Â°C is used to condense steam at 30Â°C in the condenser of a power plant at a rate of 0.60 kg/s by circulating the cooling water through a bank of 7-m-long 1.2-cm-internal-diameter thin copper tubes. Water enters the tubes at a mean velocity of 4 m/s and leaves at a temperature of 24Â°C. The tubes are nearly isothermal at 30Â°C. Determine the average heat transfer coefficient between the water, the tubes, and the number of tubes needed to achieve the indicated heat transfer rate in the condenser.
