Resistance, power and conductance from a voltage and a current — V = I·R and P = V·I, solved for a DC circuit.
Shell and head thickness to ASME VIII-1 (UG-27, UG-32), the plate to buy, the MAWP it gives you and the hydrotest pressure — with the formulas shown.
Series and parallel totals for any list of resistors — add or remove resistors and both equivalents update live.
Length change of a steel, aluminum, copper or stainless member over a temperature change, and the stress if it is restrained.
Hydraulic horsepower, brake horsepower and motor input kW for a pump from flow, head, specific gravity and efficiencies.
