How much torque is required to move a car?
Overall transmission (and power-train) efficiency of the modern electric vehicles is within 59 ..
The answer to your question is 43.2 Nm of Torque required that can be obtained with the transmission ratio value of 15..
Why does torque drop at high rpm?
At high RPM, torque drops off primarily from intake and exhaust flow restriction. Volumetric Efficiency declines because the engine can’t breathe any faster. Mechanical efficiency also declines at higher RPM, due to increased frictional resistance. This further reduces torque at the output.
Which is better hp or torque?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Does more torque mean faster acceleration?
A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … Higher torque doesn’t mean one vehicle will necessarily be faster than another, though. For example, a Ford F-250 makes 925 lb-ft of torque, while a Honda S2000 has just 162 lb-ft.
How is horsepower torque calculated?
When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.
What is HP Torque?
Torque is simply a force acting on something from a distance (i.e. a piston pushing down on a crankshaft, using that leverage to rotate it), while horsepower is torque multiplied by RPM, or a measurement of how quickly an engine can accomplish a certain amount of work.
How do you calculate engine torque?
The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels.
How do you calculate torque from HP and RPM?
To calculate torque from RPM, use this formula: Torque = (Motor Horsepower) x 63025 x Service Factor / RPM.
What is the formula to calculate torque?
A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.
How many rpm is 1 HP?
When the 1HP pump is operating in the optimal range (approx. 2700 rpm) the 3600 RPM motor is still be producing 1.5 ft/lbs of torque, while the 1800 RPM motor’s output will be somewhere between 1.5 and 3 ft/lbs.
How many ft lbs is 1 HP?
550 ft lbf1 Horsepower (Imperial Mechanical): 550 ft lbf/s.
