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 
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. Shortcut Heat Exchanger SizingUnits.

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.
