2. A shell-and-tube heat exchanger with 2-shell passes and 4-tube passes is used for cooling oil (cp= 2.0 kJ/kgK) from 125 C to 55 C. The coolant is water, which enters the shell side at 25 C and leaves at 46 C. The overall heat transfer coefficient is 900 W/m²K. For an oil flow rate of 10 kg/s, calculate the cooling water flow rate and the heat transfer area.

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.
