Water enters the side of the hull at 80°C and comes out at 60°C. It is estimated that the total heat transfer coefficient is 1000 W/m2.K. Calculate the ratio of the heat transfer and the transfer area of the latter.

In a heat exchanger, water flows through a long copper tube (inside diameter 2.2 cm) with an average velocity of 2.13 m/s. The water is heated by steam condensing at 150oC on the outside of the tube. Water enters at 15o C and leaves at 60o C. What is the heat transfer coefficient, h, for the water?
A heat exchanger is heating water on the tube side with steam condensing on the shell side. The water is entering at 45 0 F and exiting at 175 0 F. No instruments are available for measuring the tube side water flow but condensed steam from the shell side is being collected at a rate of 43 GPM. If the tube area of the exchanger is 350 Ft2 , and the overall heat transfer coefficient clean was 900 BTU/Hr.Ft2 F0, how much has the overall heat transfer coefficient changed, if at all? Note: Latent heat for water/steam at 212 0 F is 970 BTU per pound of water. A gallon of water weighs 8.34 lbs.
