Unit Converter
Convert between metric and imperial units — length, mass, volume, pressure, temperature, and more.
Pump Power & Analysis Suite
Pump hydraulic, shaft and drive power with transmission efficiency and API margin factors, plus mechanical-seal PV limit, specific speed and suction specific speed.
Horizontal Tank Volume Calculator
Calculate the liquid volume in a partially-filled horizontal cylindrical tank from diameter, length and liquid height.
Vertical Tank Volume Calculator
Calculate the liquid volume in a vertical cylindrical tank with a flat, conical or 2:1 ellipsoidal bottom from diameter, height and liquid level.
NPSHA Calculator
Calculate Net Positive Suction Head Available (NPSHA) for a pumping system.
Pressure Vessel Design Calculator
Minimum shell and head thickness for an internal-pressure vessel per ASME Sec VIII Div 1, from design pressure, diameter, allowable stress, joint efficiency and corrosion allowance.
Overhead Crane Calculator
Full design chain for a double-girder overhead crane — dead weight, wheel load, impact load, girder design load, bending moment, deflection check, hoist-rope size, motor power, hook approach and minimum wheel diameter.
Beam Deflection Calculator
Maximum deflection of a simply-supported beam under a centre point load or a uniformly distributed load, with an L/ratio serviceability check and maximum bending moment.
Heat Exchanger (LMTD) Calculator
Size a heat exchanger by the LMTD method — log-mean temperature difference, LMTD correction factor F, and required heat-transfer area for counter-current, co-current and shell-and-tube arrangements.
