16-6C Using six-tube passes in a shell and tube heat exchanger increases the heat transfer surface area, and the rate of heat transfer increases. But it also increases the manufacturing costs. 16-7C Using so many tubes increases the heat transfer surface area which in turn increases the rate of heat transfer.

This is a sample of the Heat Exchanger Sizing Calculator. To access the working calculator, please sign up for free membership trial. This is a calculator for sizing a shell and tube heat exchanger with tubeside flow fixed. With shellside and tubeside inlet/outlet temperatures fixed, the required shellside flow is calculated corresponding to given tubeside [] Shell & tube heat exchanger equations and calculations May 17, 2019 · Equation-4. Where, we get the A Overall (overall heat transfer area required) from the heat transfer rate equation (Equation-1). OD is the outside diameter of selected tube size. L is the total tube length. This equation is quite straight forward based on the geometry of the selected shell and tube heat exchanger.
Example 5.2 Miniature Shell-and-Tube Heat Exchanger A miniature shell-and-tube heat exchanger is designed to cool engine oil in an engine with the engine coolant (50% ethylene glycol). The engine oil at a flow rate of 0.23 kg/s enters the exchanger at 120°C and leaves at 115°C. The 50% ethylene glycol at a rate of 0.47 kg/s enters at 90°C.
