Horsepower and torque cross at 5252 RPM due to the relationship defined by the formula: horsepower = (torque × RPM) / 5252. This formula shows that at 5252 RPM, the units of torque (measured in pound-feet) and the conversion factor (5252) align such that the values of horsepower and torque become equal. Essentially, this is a result of the mathematical relationship between these two measures of engine performance, which is consistent across all internal combustion engines.
Torque(lb/ft) = (5252 * horsepower) / RPM
I do not know of a CHART, but the equation is: (Torque X RPM) / 5252 = Horsepower.
Horsepower is typically calculated based on the formula: horsepower = (torque x RPM) / 5252. Torque is measured in pound-feet, and RPM is the engine speed in revolutions per minute. This formula allows for the conversion of torque and engine speed into a measure of power output.
450 torque is approx. 260 HP for an engine turning at 3050 RPM or 308 HP for and engine turning 3600 RPM, based on the formula ......torque X rpm/5252 = HP
Friction power (FP) can be calculated using the formula FP = (Torque × Angular Speed) / 5252, where Torque is in pound-feet and Angular Speed is in revolutions per minute (RPM). Brake horsepower (BHP) is determined by the formula BHP = (Torque × RPM) / 5252 as well, but it reflects the engine's output power before losses from friction and other factors. Both formulas highlight the relationship between torque and RPM in measuring engine performance.
ft pounds of torque times RPM divided by 5252 equals horsepower ..... In your question one peice of info is missing in order for someone to give you an answer .....(revolution per minute )
Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have been working at the rate of one horsepower. In this case, you'd have expended one horsepower-minute of energy. There are other definitions but as a whole they say approximately the same as in energy consumed for actual work.
To calculate horsepower you need the car's torque numbers. To find the horsepower, the formula HP=(RPM*T)/5252. The "HP" stands for "horse power", the "T" in the formula stands for "torque " and RPM stands for the RPM values. To calculate the horse power of an electric motor, you use the formula HP= (V*l*eff)/746. V=voltage, l=amps, and eff= efficiency.
The torque output of a 5 horsepower (hp) engine can vary depending on its design and operating speed. However, a common approximation is that at 3,600 RPM, a 5 hp engine typically produces around 15-20 foot-pounds of torque. To calculate torque, you can use the formula: Torque (ft-lbs) = (Horsepower × 5252) / RPM. Therefore, at 3,600 RPM, a 5 hp engine would yield roughly 15.5 ft-lbs of torque.
225 horsepower at 4200 RPM and 300 lb/ft torque at 3200 RPM
I believe that is the maximum horsepower and torque and at what RPM they occur
225 horsepower at 4200 RPM and 300 ft-lbs torque at 3200 RPM
