Input Horsepower (Power Supplied to Driver)
 Brake Horsepower (Driver Load) : Driver Efficiency : Result :
##### Definition :
• The total power used in operating a pump and motor.
• The Horsepower (hp) is a unit of measurement of power or the rate at which work is done, usually in reference to the output of engines or motors.
• Horsepower refers to the power an engine produces and then the input power delivered by the motor to the pump is called brake horsepower (bHp).
• Then, The difference between the brake horsepower and hydraulic power is the pump efficiency.
• The water horsepower is the minimum power required to move water. Then, it is the power a pump would require if the pump was 100 percent efficient.
• The water horsepower can be determined if the flow rate of the water and then the force (pressure) required to produce that flow is known.
##### Formula :
• The formula for the calculation is given below.
• Result = Brake Horsepower / Driver Efficiency.
• Beside the formula this calculator works.
##### How to Calculate ?
• First, Enter the Brake Horsepower. Then,
• Second, Enter the Driver Efficiency. Then,
• Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
• Finally, follow these steps to get the result.
