Steam is condensed on a bundle of 500 tubes through which there is a flow of cold water. The outside diameter of tubes is 5cm, and the overall heat transfer coefficient (based on outside area) is 800 W/m^2 K. The water enters at 20C with a flow rate of 0.5 kg/s. If the outlet temperature is 50C, how much steam is condensed on each tube, and how long is the tube bundle? The specific heat capacity of water at 35C is 4180J/kg-K, and enthalpy of vaporization of steam at atmospheric pressure is 2.257 * 10^6 J/kg.
