Heat Transfer

  1. Nov 1, 2009 #1
    1. The problem statement, all variables and given/known data

    Saturated liquid H2O @ 500 kPa flows in a metal pipe, 5 cm inner diameter and k=40 W/m K, with wall thickness 3 mm @ a rate of 2 kg/s. The pipe is exposed to ambient gas @ 500 degrees C with h=100 W / squared K. The water is being boiled to come out as saturated vapor @ 500 kPa. Assume the H2O temp is uniform and there is no inside convective layer. Find the total rate of heat transfer that must take place and the needed length of pipe.
