Physics Calculators.

Five engineering and physics calculators aimed at real design work rather than textbook exercises. Fluid Mechanics covers Reynolds number for identifying flow regime, boiler feed pump sizing including net positive suction head, and lb/hr to GPM conversion through fluid density. Kinematics holds an RPM to FPM converter for belt and roller surface speed, and an arrow speed calculator that accounts for front-of-centre balance as well as draw weight and draw length. Each page gives the governing equation, the units it expects, and the assumptions that stop the result being valid outside a normal working range. Where a figure is quoted from a published standard, that standard is named so it can be checked.
