Saturated liquid water at 30°C and 1.8 m/s enters a long brass (k = 108 W/m-K) condenser tube with inner diameter of 1.45 cm and outer diameter of 1.6 cm. The heat transfer coefficient for condensation at the outer surface of the tube is 12,232 W/m2-K.
What is the convection coefficient of the water flowing in the tube?
Calculate the overall heat transfer coefficient based on the outer surface of the tube.
