What term is used to express the rate at which work is done?
efficiency. Energy output is horsepower
Who created the term horsepower?
The term "horsepower" was created by Scottish engineer James Watt in the 18th century. Watt used the term to help potential buyers of his steam engines understand the power output in a way that was relatable to them.
What term is used to describe the rate at which work is done?
The term used to describe the rate at which work is done is power. It is typically measured in watts (W) or horsepower (hp) and represents how quickly energy is transferred or work is performed.
What is the term given to describe the rate at which a machine can do work upon other objects?
The term used to describe the rate at which a machine can do work upon other objects is power. Power is measured in watts (W) or horsepower (hp) and indicates how quickly work is done.
Who invented horsepower?
James Watt did, when he needed to compare the power of his engines to the power a horse could output. 1 hp = 746 w John Sandy John SandyThe term horsepower was invented by James Watt, who used it to give coal miners an estimate of the power his steam engine could produce in terms of the number of horses it could replace in pulling coal bins.
What was the term used to describe a engine power?
Horsepower and Torque
What term is used to express the rate at which work is done?
efficiency. Energy output is horsepower
Who invented the concept of horsepower?
The concept of horsepower was first introduced by James Watt, a Scottish engineer, in the late 18th century. Watt used the term to compare the power of steam engines to that of horses, providing a more relatable way to understand and measure engine power.
IN reference to autos What is the difference between brake horse power and barrel horse power?
Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine RPM and a scaling constant to give horsepower). Never heard of Barrel H.P.
What is meant by brake horse power in cars?
Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the use of a band brake to measure torque during the test (which is multiplied by the engine speed in revs/sec and the circumference of the band to give the power).
Who created the term horsepower?
The term "horsepower" was created by Scottish engineer James Watt in the 18th century. Watt used the term to help potential buyers of his steam engines understand the power output in a way that was relatable to them.
What is the meaning of motor of 50 horsepower?
Horsepower is a unit of power. For an electric motor, the horsepower is defined as 746 watts of power. For a 50 horsepower motor, that translates to 37.3 KW.The origin of the term came from an attempt to equate the power of a horse versus the power of a steam engine. Early ratings came out to be about 33,000 foot-pounds per minute or about 550 foot-pounds per second. Today, the term varies, depending on the application. For electric motors, again, it is 746 watts.
What does bhp brake horsepower mean?
Brake horse power is the power output of the drive shaft on an engine without the power loss caused by the gears, transmission, friction, etc. The actual useful horsepower delivered to the propellor or wheel is called the shaft horsepower. Its also called effective ,true, wheel horsepower as well as other terms. The term horsepower is is not a good measurement of power as there asre too many different systems of measuring horsepower. The current trend is to use kilowatts or megawatts.
Why it is called horsepower and not elephant power?
The term comes from an engineer who was working on steam engines. He calculated the average amount of weight a pony could pull a certain distance. He chose ponies because they were used to move coal out of mines. He decided to increase that average by 50% and call it horse power. It quickly became an easy way to measure power in cars. The people who used this term had much more contact with horses than elephants so horse power would make more sense to them. Had the term been established in Africa or Asia elephant power could be have been a likely candidate.
How many humans equal one horsepower?
Power is defined as 'the rate at which work is done'. In SI, power is measured in watts. In the Imperial system of measurements, power is measured in horsepower.So, you cannot 'convert power into horsepower'. Horsepower, together with the watt, are simply units in which power is measured.
What is one horsepower?
One horsepower is equivalent to 746 watts ( = joules of energy per second) or 550 ft.lb (force) of work per second.The horsepower or hp is the Imperial unit of measurement for power."Power" is the scientific term used to describe "capacity to perform some work".These days, in most countries, it has been replaced by an SI unit, the watt (or, in practice, kilowatt).The term brake horsepower refers to the rated output power of a machine, which is not to be confused with the amount of input power it requires to be able to generate that amount of rated output power.In the case of a car engine, the brake horsepower (or kilowatts) is the power remaining after all the losses have been taken into account. (Heat emitted, gearbox friction, etc.) In other words, output power (brake power) is input power minus losses.For more information see the Related link shown below.
What is the most powerful Acura car?
A vehicles "power" is usually measured by the term "horsepower". The Acura model with the most horsepower is the Acura TL-SH AWD. This car first was first released to the market in 2012. It boasts 304 horsepower. Other Acura models have horsepower around 280 HP.
