A shell and tube heat exchanger consists of one shell with 100 thin-walled tubes of 15 mm diameter in a double pass arrangement. The total surface area is 45 m^2 and the overall heat exchanger conductance is 200 W/m^2?K. Water enters the tubes at 15ºC and 6.5 kg/s. Hot gases having properties of air at 200ºC and 5 kg/s flow through the shell. Determine (a) gas outlet temperature and (b) water outlet temperature.
