Both calculators run independently — change the inputs on either side to compare results.
Chemical Engineering
Pump NPSH Calculator
Calculates the Net Positive Suction Head available (NPSHa) for a centrifugal pump installation to verify cavitation will not occur. Use it whenever sizing pump suction lines or repositioning a pump relative to its fluid source.

Chemical Engineering
Fenske Equation Calculator
Compute the minimum number of theoretical equilibrium stages required for a binary distillation separation using the Fenske equation. The "best case" stage count at total reflux — actual columns need more stages because they operate at finite reflux.
