Difference between horsepower and torque?
Torque is the measurement of turning force. A wrench applies torque to a bolt. A motor or engine provides torque to do work. Horsepower is the measurement of the work done or ability to do work. This is done by taking the speed the engine is operating at (RPM) and what torque it is producing and applying a formula to give a horsepower rating.
The amount of work done by heat engine equals the amount of what?
the amout of work done on the engine
How much horsepower is 7 torque?
Torque has nothing to do with horsepower. It is purely a measure of force, whereas horsepower is a measure of how much work can be done over time.
How is horsepower attained?
By an engine or machine working ( force x distance = work)
What is engine torque?
Toruqe is the amount of rotational force the engine generates. Horsepower is work performed in a straight line.
What engine torque?
Toruqe is the amount of rotational force the engine generates. Horsepower is work performed in a straight line.
What term is used to express the rate at which work is done?
efficiency. Energy output is horsepower
What is mean by hp?
Horsepower (hp) is unit of measurement of power, the rate at which work is done.
How did work done by the steam engine compare to work done by horses?
the steam engine was quicker and stronger than hoses
Who was the inventor of steam engine and what is horsepower?
There was no one inventor of the steam engine, although James Watt and Thomas Newcomen were among the first to create a workable engine. Horsepower is a measure of energy needed to do work. One horsepower is required to lift 75 kg 1 meter in 1 second.
What was the horsepower of the 1st steam engine?
The first steam engine was Hero's turbine, it is unknown what the horsepower output of it was. It was used as an item of curiosity, and did no real work. The first practical (useful) steam engine was the Newcomen pumping engine, used to pump water out of mines, it was an improvement over Savery's pump (which did use steam but not an engine) in that it more efficiently made use of the steam, it is estimated that the work output of this engine would have been about 10 to 30 horsepower. The engine used the vacuum created by condensing the steam to drive it. The Boulton-Watt engine was the first practical engine that used the power of the expansion of steam to drive the piston, in both directions, thus improving the efficiency of the engine. The horsepower of this engine was about 10 to 45 BHP (brake horsepower).
Is it true that power is the rate at which work is done and is generally measured in horsepower?
no, power is calculated in watt
