How many rpm is 1 HP?
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..
Is torque dependent on RPM?
The torque varies in different vehicles depending on the RPM. … The torque of every vehicle is calculated based on the RPM at any given point of time. This basically means that the Torque of a vehicle’s engine depends on the RPM, however the RPM of the vehicle’s engine is determined on the power output of the engine.
Is torque directly proportional to RPM?
Note that at 5252 RPM, torque and HP are equal. At any RPM below 5252, the value of torque is greater than the value of HP; Above 5252 RPM, the value of torque is less than the value of HP.
How much torque does a 1 hp motor have?
The 1800 RPM, 1HP motor produces 3 ft. lbs of torque at 1800 RPM. The 3600 RPM, 1HP motor produces 1.5 ft.
Why does torque change with RPM?
If you hold the rpm constant, then power varies with torque, and if you hold torque constant, power varies with rpm. … The more air and gasoline, the more powerful the engine will be at a GIVEN rpm, because more fuel air mix translates to greater torque and thus greater power.
What RPM does horsepower and torque cross?
5,252 RPMWhy do horsepower and torque cross at 5,252 RPM? They’re interwoven, important for the speed and acceleration of your vehicle, and the desire of every gearhead.
Does higher rpm mean more power?
Higher revolutions per minute equate to more fuel burnt in the same amount of time and more power produced. … Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower. In a straight line race, higher RPMs take precedence.
How much BHP is 1 HP?

What is better to have torque or horsepower?
In simple terms, you can think of torque as a measure of how much work your vehicle can do. A healthy amount of torque is what pulls you up hills and helps you haul trailers around. Horsepower is all about speed and keeping your car moving. In general, more horsepower means you’re getting a faster car.
Is torque a power?
Back to Berra’s theorem, torque is the capacity to do work, while power is how quickly some strenuous task can be accomplished. In other words, power is the rate of completing work (or applying torque) in a given amount of time. Mathematically, horsepower equals torque multiplied by rpm.
How horsepower is calculated?
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.
What is the constant 5252?
(Why the puzzling 5252 constant? One Horsepower is defined as 33,000 lb-ft / minute. The circumference of a one-foot radius circle is 6.2832 feet. Since these are both constants, you can divide 33,000 by 6.2832 to get 5252, reducing the equation to a very simple approximation.)
