Both calculators run independently — change the inputs on either side to compare results.
Engineering
Power Transmission Calculator
Converts torque (N·m) and rotational speed (rpm) into mechanical power in kilowatts. Use it when sizing motors, drives, or shafts, or when checking whether a drivetrain can handle a given load without overheating.

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.
