WebA simple answer is, historically, about 8,000 hp - the PRR Q-2 class was so rated. But power is not a good way to evaluate a steam locomotive. It’s a stored power system, the boiler full of high pressure gas, fed by a system that can replenish that gas, means that a steam engine is a constant torque device.

Modern vs. Vintage: Horsepower through the years - Autoblog

Web20 dec. 2005 · The first calculation you want to do is multiply the torque and the engine speed. [1] For example, a Porsche generates 480 of torque at 2,500RPM. Expressed in … Web18 jan. 2016 · To calculate horse power for rotating objects you need the formula: HP = (Torque * RPM) /5252 But then you need to calculate torque: T = Force (lbs) * Radius (feet) So the combined formula would be: HP = ( Force (lbs) * Radius (feet) * RPM) / 5252 WebTwo parts to this – first we take the wheel horsepower figure (WHP) that the car has made on the dyno. BHP-WHP= Horsepower Loss. We then divide HP loss by BHP and multiply by 100 to get our drivetrain loss percentage. How is flywheel HP calculated? The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252. hilton islington upper street
