Question

Saturated steam at 60 ºC is condensed over an array of 100 horizontal tubes, each with a diameter of 1.2 cm and a length of 3 m. The tube surfaces are maintained at a uniform temperature of 30 ºC. a) What is the pressure of the steam? _____________ kPa. (Note that this could have been given instead of steam T.) Determine the condensation rates on the tubes for b) a rectangular array of 5 tubes high by 20 tubes wide and c) a square array of 10 tubes high by 10 tubes wide. Compare and discuss the results of b) and c). d) Brief physical explanation of how the results compare:
