Horsepower in inches per second?

In summary, the conversation is about determining the amount of horsepower generated by moving 19 lbs 1-1/2 inches in 1 second. The experts suggest doing a unit conversion and clarify that the statement that 1 horsepower is generated by moving 300 lbs 100 feet in one minute may not be entirely accurate.

Hello Wizards!

O.K. I know that 1 horsepower is generated by moving 300 lbs 100 feet in one minute.

The question I seem unable to answer is...

How many horsepower is generated by moving 19 lbs 1-1/2 inches in 1 second?

Help please ( my brain is exploding )

Best Regards,

Bill

How many inches in a foot? How many seconds in a minute? Just do the unit conversion.

The way that's worded makes it sound like the 300lb is the weight of the object, not the force...

Like a lot of things people "know", this sounds like it might be true. However, the facts get in the way of a good story.

One horsepower = 550 foot-pounds of work done in one second, or 33,000 foot-pounds of work done in one minute.

Whether it actually takes 300 foot-pounds of work to move 300 pounds a distance of one foot is another story.

What is horsepower in inches per second?

Horsepower in inches per second is a unit of measurement used to calculate the power output of an engine or motor. It represents the amount of work that can be done in one second, with one horsepower being equal to 33,000 foot-pounds of work per minute.

How is horsepower in inches per second calculated?

Horsepower in inches per second is calculated by taking the torque output of an engine or motor (measured in inch-pounds) and multiplying it by the rotational speed (in revolutions per second) and dividing by 63,025.

What is the difference between horsepower in inches per second and horsepower in feet per second?

The difference between horsepower in inches per second and horsepower in feet per second is simply the unit of measurement used for the rotational speed. One horsepower in feet per second is equal to 12 horsepower in inches per second.

Why is horsepower in inches per second important?

Horsepower in inches per second is important because it is a standard unit of measurement used to compare the power output of different engines and motors. It allows scientists and engineers to determine the efficiency and performance of a machine.

Can horsepower in inches per second be converted to other units?

Yes, horsepower in inches per second can be converted to other units of power, such as watts or kilowatts. However, it is important to note that horsepower in inches per second is a measure of rotational power, while watts and kilowatts are measures of electrical power.
