Question

Water at 15degree Celsius passes through 2cm internal diameter copper tubes at a rate of

0.55kg/s. Determine the pumping power per meter of pipe length required to maintain this flow
at the specified rate.

Answer 1

Im not really sure tbh

Step-by-step explanation: Water at 15°C is heated by passing it through 2-cm internal-diameter thin-walled copper tubes. Heat is supplied to the water by steam that condenses outside the copper tubes at 120°C. If water is to be heated to 65°C at a rate of 0.2 kg/s, determine (a) the length of the copper tube that needs to be used and (b) the pumping power requirement to overcome pressure losses. Assuming the entire copper tube to be at steam temperature of 120°C
