Condensation of Steam on Vertical Tubes. Steam at 1 atm pressure abs and 100°C is condensing on a bank of five vertical tubes each 0.305 m high and having an OD of 25.4 mm. The tubes are arranged in a bundle spaced far enough apart so that they do not interfere with each other. The surface temper- ature of the tubes is 97.78°C. Calculate the average heat-transfer coefficient and the total kg condensate per hour.
