Mechanical
Pump Head and Power Calculator
Calculate the hydraulic power required to drive a pump based on flow rate, total head (static plus friction), fluid density, and pump efficiency. Use this when selecting a pump motor or auditing energy consumption in a piping system.

Mechanical
Screw Thread Stress Calculator
Calculates the shear stress on screw threads given applied force, thread geometry, and engagement length. Use it when verifying that a threaded joint won't strip under tensile or torsional loading.
