Maximum deflection and bending moment of a simply supported beam under a centre point load or a UDL, with an L/ratio serviceability check.
Size a heat exchanger by the LMTD method — log-mean temperature difference, correction factor F, fouling, and required area for counter-current, co-current, and shell-and-tube.
Liquid volume in a partially filled horizontal cylinder, sphere, or cylinder with 2:1 elliptical heads, from diameter, length, and liquid height.
Net Positive Suction Head available from an energy balance at the pump suction, with the margin against the pump's NPSHR.
Preliminary design chain for a double-girder overhead crane — dead weight, wheel load, impact, girder moment and deflection, rope size, motor power, and wheel diameter.
Minimum shell and head thickness for an internal-pressure vessel per ASME Section VIII Division 1, with corrosion allowance and the next standard plate.
Hydraulic, shaft, and drive power for a centrifugal pump with the API 610 rated-power margin, plus seal PV, specific speed, and suction specific speed.
Convert 327 engineering units across 44 categories — pressure, flow, viscosity, torque, thermal conductivity, section modulus — in SI, metric and US/Imperial.
Liquid volume in a vertical cylindrical tank with a flat, conical, or 2:1 ellipsoidal bottom, from diameter, shell height, and liquid level.
