EML 4147C 1. (11.39) Saturated water vapor leaves a steam turbine at a flow rate of 1.5 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17 °C and is to leave at 57 °C. Assuming an overall heat transfer coefficient of 2000 W/m 2 ∙K, determine the required heat exchanger surface area and the water flow rate. After extended operation, fouling causes the overall heat transfer coefficient to decrease to 1000 W/m 2 ∙K. To completely condense the vapor, there must be an attendant reduction in the vapor flow rate. For the same water inlet temperature and flow rate, what is the new vapor flow rate required for complete condensation?

2. A novel thermosyphon system similar to your laboratory pool boiling experiment has been proposed to cool computer chips. This device uses saturated fluorocarbon as the working fluid. The chip is brazed to the bottom of a cuplike container, within which heat
