\(\begin{array}{l}\text{Horse Power , HP} = Weight \times \left ( \frac{velocity}{234} \right )^{2}\end{array} \) This formula is applied to calculate the speed or velocity at the end of the run. Weight includes the mass of the whole body.
19 paź 2016 · The velocity of a free falling object with air resistance with respect to time t can be modeled by this equation$^2$: $$v = \sqrt{\frac{2mg}{pAC_d}} \tanh\left(t\sqrt{\frac{gpAC_d}{2m}}\right)$$ To modify this to model to suit the situation, simply replace "g" with a(t) since the object is accelerating due to the force of the engine, not gravity:
For the electric motors, we can calculate the power or horsepower from the torque and speed. For example, if we have a motor with 3,000 rpm and 6 in-lbf then the horsepower can be calculated below. Horsepower = \( \frac{300 × 6}{63025} \)
8 lut 2024 · It’s easy to calculate a car’s horsepower if you know its torque and engine speed, using the formula RPM (rotations per minute) x T (torque)/5,252 = HP (horsepower). You can usually find the torque numbers listed in the technical specs section of your owner’s manual.
27 lip 2016 · To calculate horsepower, you will need to know the time it takes for an object to travel a certain distance and the weight of the object. The formula for calculating horsepower is: HP = (Weight x Distance) / (Time x 550). This formula assumes that the distance is in feet, time is in seconds, and weight is in pounds. 2.
The power (P) generated by the engine in horsepower can be calculated if we know the force (F) exerted by the vehicle (which can be calculated using the weight of the vehicle), and its velocity (v). The formula is:
motor horsepower. For many applications, it is possible to calculate the horsepower required without actually measuring the torque required. The following useful formulae will help: Conveyors HP (Vertical) = Weight (lb) x Velocity (FPM) 33,000 HP (Horizontal) = Weight (lb) x Velocity (FPM) x Coefficient of Friction 33,000
