# Computer program for calculating the surface area of heat exchanger

Make a computer program for calculating the surface area of heat exchanger using the process and parameter described in example 2-2.

The question is the following:

A heat exchanger with one shell pass and eight tube passes raises 100,000 lbm/hr(variable 1) of water from 180°F(variable2) to 300° F (variable 3). The tube-side fluid is air (Cp=0.24 Btu/lbm °F (Variable 4)), which enters at 650 °F (Variable 5) and exits at 350 °F (variable 6). If U= 5 Btu/hr-ft^2-°F (Variable 7), find the surface area required.

Expectations:

[1] Define your problem by making a sketch

[2] Make a flow chart for computing area and show equations for each step

[3] Write program for calculation of surface area. However, make program generic by making each of the question value a variable that you can input.
