Mechanical
Heat Exchanger Effectiveness Calculator
Calculate the actual heat transfer rate of a heat exchanger using the effectiveness-NTU method. Useful for sizing or evaluating shell-and-tube, plate, or counterflow heat exchangers.

Mechanical
Pressure Vessel Wall Thickness Calculator
Calculate the minimum required wall thickness for a cylindrical pressure vessel shell under internal pressure, per the thin-wall design formula with a corrosion allowance. Essential for ASME-code vessel design and safety verification.
