Water is flowing inside a horizontal 1- in. schedule 40 steel pipe at 37.8°C and a velocity of 1.52 m/s. Steam at 108.3°C is condensing on the outside of the pipe wall and the steam coefficient is assumed constant at 9100 W/m2 •K. (a) Calculate the convective coefficient h; for the water. (Note that this is trial and error. A wall temperature on the inside must be assumed first.) (b) Calculate the overall coefficient Ui based on the inside area and the heat transfer flux q/A; in W/m?.
