## How is HP calculated?

Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed.

For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below..

## What is 1HP equal to?

The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.

## How is RPM related to speed?

RPM is the number of revolutions the drive shaft of your car is making per minute. Speed is the linear velocity of the vehicle. … This happens because of the GEARS in your transmission. Different gears give different rates of rotation to the wheels of the car for the same number of RPMs of the car’s drive shaft.

## How many ft lbs is 1 HP?

550 ft lbf1 Horsepower (Imperial Mechanical): 550 ft lbf/s.

## How many horsepower is a human?

1.2 hpWhen considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours.

## How many watts is a 1 hp motor?

746 wattsOne electric horsepower is equal to exactly 746 watts.

## What is difference between HP and kW?

James Watt is also the reason we have the measurements watt and kilowatt, most commonly used to measure electricity. Obviously, a kilowatt is 1,000 watts. … To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.

## How many horsepower is 12 amps?

## How many kW is a 1HP aircon?

0.7457 kW1 hp = 745.7 watts. Because 1 kW = 1,000 watts, 1 hp = 0.7457 kW.

## How do you calculate HP RPM?

Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

## Is 1HP equal to 1 horse?

Does one horsepower equal one horse? Not quite. It’s a common misconception that one horsepower is equal to the peak power production of a horse, which is capable of a maximum of around 14.9 horsepower. By comparison, a human being is capable of approximately five horsepower at peak power production.

## Why horsepower is called so?

When the steam engine began to do the work of horses in the mines during the early 1800s, the mine owners began to ask how many horses an engine would replace. James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented.

## How RPM of motor is calculated?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

## How many horsepower is 3450 rpm?

## What is rpm in a car?

CARS.COM — RPM stands for revolutions per minute, and it’s used as a measure of how fast any machine is operating at a given time. In cars, rpm measures how many times the engine’s crankshaft makes one full rotation every minute, and along with it, how many times each piston goes up and down in its cylinder.

## How do you convert rpm to power?

Power is calculated by the equation (HP = Torque x RPM/5252)

## What is the rpm of 1HP motor?

## How many HP is RPM?

5,252 rpmOne horsepower is equal to 33,000 foot-pounds of work per minute. Add in the equations relating to torque and velocity, and you’ll find that horsepower always equals torque multiplied by rpm, divided by 5,252. Canceling out the equal variables, you wind up with horsepower equaling torque… at 5,252 rpm.
