what is the practical difference between torque and horsepower?
100352
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.

In the GLS, the engine produced 148 horsepower at 6,500 rpm and 131 foot-pounds of torque at 4,700 rpm. In the SE, it generated three fewer horsepower and one less foot-pound of torque. From behind he wheel, though, even the most sensitive drive would be hard-pressed to notice any difference.

The difference between the two is, obviously the pressure generated by the spinning turbos. While higher pressure will provide more boost, it doesn't necessarily mean more power (as in HPs).

Torque is what allows a car to jump off the starting line like a rocket. Torque is the measure of how much force causes an object to rotate. Typically measured in pounds per foot, an engine's torque value determines its acceleration. ... They happen when the car has enough torque to support that kind of rapid acceleration.

Horsepower A unit of rate of doing work equal to 33,000 foot pounds per minute or 745.8 watts (Brit.), 746 watts (USA), or 736 watts (Europe). Hydroelectric Power Electric current produced from water power.

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

A SOHC engine with 16 valves produces better torque than a DOHC with the same number of valves due to the DOHC engine additional weight. But the DOHC will produce more horsepower at higher speeds. The SOHC has better low-end torque while the DOHC has more top end power while the two hold the same number of valves.

The horsepower presents the engine power, ability to perform work in a unit of time. The cubic centimetres signify the engine volume, i.e. the sum of the volumes of all cylinders. In simple terms, a vehicle gets the power (in horsepower) by combusting fuel and air in the cylinder (with volume in cc).

One horsepower is a unit of power that equals the work done in lifting 550 pounds one foot in one second. One manpower = a unit of power based on the rate at which a man can work; approximately 75 watts, or about one tenth of a horsepower. In other words, it takes ten strong men to do the work of one horse.

A 4-pole motor has about 3.0 ft. -lbs of torque per horsepower where a 2-pole motor has 1.5 ft. ... At 60 Hz, a 4-pole motor is about 1800 rpm where a 2-pole motor is 3600 rpm. Thus, the 4-pole motor provides higher efficiency, higher torque per unit of volume and weight.

As you can clearly see Torque is maximum at mid rpm's whereas Power is maximum at the top of the rev band. This is because max Torque occurs at the maximum Volumetric Efficiency of the engine. Volumetric efficiency is the breathing ability of the engine or how efficiently your engine breathes (sucks in air).

Units. The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.

1. HP is the output horsepower rating of an engine, while BHP is the input brake horsepower of an engine. 2. B HP is the measurement of an engine's power without any power losses, while HP is BHP less the power losses.

What are the relationships between speed, torque, wheel size, and RPMs? There are several. Generally speed and torque are opposed to each other. With a small gear (More speed, less torque) turning a larger gear (less speed, more torque) you sacrifice speed to gain the torque.

In an electric motor, the mechanical power is defined as the speed times the torque. Mechanical power is typically defined as kilowatts (kW) or horsepower (hp) with one watt equaling one joule per second or one Newton-Meter per second. Horsepower is the work done per unit of time.

top end power dont nessecerely mean faster it just refers to the power you have at the top of an RPM range... bottem end power refers to the power you have at lower RPMs..

Electrical horsepower is a measure of power equivalent to 746 watts while kilovolt-amps measure apparent power. Because power factor and motor efficiency reduce the amount of actual work performed for the amount of apparent power in the circuit, the conversion from horsepower to kVA requires a formula.
