Effectiveness NTU Method is used to find exit temperature in a shell and tube heat exchanger with one shell and two tubes. You'll learn how to find Heat Capacity Rate, Heat Capacity Ratio, Heat Transfer Effectiveness, and NTU net thermal units. One of the flows is in condensation, which gives it an infinite specific heat capacity, which simplifies the equations, but in a sort of weird way.

Saturated water vapor at 100 C condenses in a one shell and two-tube heat exchanger with a surface area of 0.5 m2 and an overall heat transfer coefficient of 2000 W/m2K. … Determine (a) the heat transfer effectiveness, (b) the outlet temperature of the cold water, and (c) the heat transfer rate for the heat exchanger.
