Engineering
Pump Head & Power Calculator
Calculates the brake horsepower a pump motor must deliver to move a fluid at a given flow rate against static head and pipe friction losses. Use it when selecting pumps for irrigation, HVAC, chemical processing, or water supply systems.

Engineering
Thermal Expansion Calculator
Calculates how much a material elongates when its temperature changes, using the linear thermal expansion formula. Use it when designing pipework, rail joints, bridge expansion gaps, or any structure subject to temperature fluctuations.
