A standard 50mm diameter steel pipe (k=147,6W/m2K) has water flowing through it under such conditions that the individual water film coefficient is 2 839W/m2K. Steam with an individual film coefficient of 11356W/m2K is condensing on the outside of the pipe. The overall (T) at the point where water enters the heater is 65,5C and the overall (T) at the exit from the heater is 10C. A logarithmic-mean temperature difference should be used. The pipe is 3,0m long and the wall thickness of the steel pipe is 5mm. Calculate the amount of heat gained by the water per hour
