Standardized Calculation Modules
Built to international design codes. Every module returns exact mathematical derivations, stress checks, and standard allowances.
Horizontal Tank Volume
Calculate liquid volume, capacity, fill percentage, ullage, and mass for horizontal tanks with flat, spherical, or ASME 2:1 elliptical heads.
Vertical Tank Volume
Compute accurate inventory volume and ullage for vertical vessels with flat bottom, conical hopper, or dished ellipsoidal heads.
Pump NPSHA & Cavitation
Determine Net Positive Suction Head Available, Antoine vapour pressure fit, suction piping friction loss, and evaluate API margin.
Pump Shaft Power & PV
Calculate hydraulic & shaft brake power, electric motor rating, specific speed (Ns, Nss), and mechanical seal PV limit checks.
Pressure Vessel Shell & Heads
UG-27 cylindrical shell required thickness, UG-32 2:1 ellipsoidal and hemispherical heads, allowable stress and MAWP verification.
Overhead Crane Girder & Hoist
Calculate bridge girder dead/live loads, maximum bending moment, S/800 deflection verification, and wire rope MBL safety factor.
Plus unit conversion, LMTD heat exchanger and beam deflection tools
