 # Question: How Do You Calculate HP?

## What does 1 hp motor mean?

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended.

A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).

To convert from horsepower to watts, multiply by 746..

## How much CC is equal to 1 HP?

Many people have asked for a relationship between horsepower and cc or how many cc in a hp. The short answer is about 14 to 17cc = 1 hp or about 1 cu.in. = 1 bhp for an ordinary, basic car.

## How many watts is a 1 hp motor?

746 wattsOne electric horsepower is equal to exactly 746 watts.

## How fast is 1hp?

In other words, your engine have a 1 horsepower if it corresponds to the power of horse lifting 550 pounds to 1 foot in 1 second. Therefore, horsepower is a unit expressed in the foot-pound-second (fps) system that fulfills the relation 1 HP = 550 foot-pounds per minute.

## Can you convert psi to CFM?

The relationship between CFM and PSI is just linear. if you get 8 CFM at 120 psi, you will get 4 CFM at 60 PSI.

## 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 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.

## What is the value of 1 hp?

746 wattsThe 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.

## 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.

## How many CFM is equal to 1 HP?

3-4 CFMA rule of thumb is that each 1 HP motor size generates about 3-4 CFM of compressed air flow at about 90 PSI.

## What is HP in compressor?

Horsepower (hp) measures the amount of mechanical energy a device uses to complete a task. An air compressor converts electrical energy into mechanical energy to move air or liquid particles. … A single unit of horsepower is equivalent to 745.8 watts.

## How many HP is 200cc?

10 horsepowerOn average you could expect around 5–10 horsepower from a 200cc engine, but it can vary hugely. CC is a measurement of volume or size where Engine horsepower is a measurement of power output at certain rpm.

## How many HP is 170cc?

The engine produces 1634.5 Joules per cycle, so at 120 RPM it produces 1634.5 Joules per Second. A Horsepower is 745.7 Joules per second, so the 420 cc engine produces at best 2.19 HP at 120 RPM. Horsepower scales with RPM, so it would produce at best 65.76 HP at 3600 RPM.

## What is the meaning of 1 hp pump?

Water horsepower is the minimum power required to move water. In other words, it is the power a pump would require if the pump was 100 percent efficient. … This equation was derived knowing that one horsepower is equal to 550 foot-pounds per second.

## Does HP matter in air compressor?

HP is horsepower, or the amount of work that a motor can perform. HP is not as important as pressure and flow in determining if your compressor will work for you, as newer & more efficient compressors can do more with less HP!
