1 125 Consider the flow of saturated steam at 270 1 kPa that flows through the shell side of a shell and tube heat exchanger while the water flows through 4 tubes of diameter 1 25 cm at a rate of 0 25 kg s through each tube The water enters the tubes of heat exchanger at 20 C and exits at 60 C Due to the heat exchange with the cold fluid steam is condensed on the tubes external surface The convection heat transfer coefficient on the steam side is 1500 W m K while the fouling resis tance for the steam and water may be taken as 0 00015 and 0 0001 m K W respectively Using the NTU method deter mine a effectiveness of the heat exchanger b length of the tube and c rate of steam condensation Saturated steam UU 60 C 20 C Water
