Fluid Mechanics
Pump Affinity Laws Calculator
Predict how a centrifugal pump's flow, head, and power change when its speed or impeller size is altered, using the pump affinity laws. Ideal for engineers optimising pump operation or evaluating variable-speed drives.

Fluid Mechanics
Pipe Flow Velocity Calculator
Find the average velocity of fluid flowing inside a circular pipe from the volumetric flow rate and pipe diameter. Essential for checking whether flow falls within recommended velocity limits to avoid erosion or excessive head loss.
