Pump power and specific speed
FREE
Calculates pump power using total head, specific gravity (density), flow and pump efficiency. Uses Imperial and metric units. Offers a pull down menu with a list of specific gravities for many liquids.
Head to pressure relationship
FREE
Calculates head based on pressure and specific gravity (density), or pressure based on head. Imperial or metric units available
Pipe friction loss
FREE
Calculate pipe friction loss for laminar or turbulent flow, for any pipe diameter, flow, pipe roughness, liquid viscosity and pipe length. Uses Imperial or metric units.
Velocity vs. flow in pipes
FREE
Calculate velocity of a liquid in a pipe based on flow and pipe inside diameter, or calculate diameter or flow vs. any other two parameters. Imperial and metric units are available.
