## What is the relationship between HP and torque?

Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.

What is 1 horsepower?

horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

What horsepower is 5252?

We need to get to horsepower, which is 550 foot-pounds per second, using torque (pound-feet) and engine speed (RPM). If we divide the 550 foot-pounds by the 0.10472 radians per second (engine speed), we get 550/0.10472, which equals 5,252.

### How many rpm is 1 hp?

Is torque Better Than Horsepower?

“Below 5252 RPMs any engine’s torque will always be higher than its horsepower, and above 5252 RPMs any engine’s horsepower will always be higher than its torque. At 5252 RPMs the horsepower and torque will be exactly the same.” — revsearch.com

What is the equation to calculate torque?

Formula E racecars are limited to 335PS (250kW) but this twin motor, four-wheel drive beastie boasts a system output of 815PS, split between a 250kW motor up front and 350kW unit behind. DS says torque at the wheels hits 8000Nm. It should go well then but

• How to calculate horsepower formula?

Water horsepower = minimum power required to run water pump

• TDH = Total Dynamic Head = Vertical distance liquid travels (in feet)+friction loss from pipe
• Q = flow rate of liquid in gallons per minute
• SG = specific gravity of liquid (this equals 1 if you are pumping water)
