Horsepower physics equation
WebMay 13, 2024 · pt0 = p0 + .5 * r * V0 ^2 where r is the air density and V0 is the velocity of the aircraft. Downstream of the disk, pte = p0 + .5 * r * Ve ^2 where pte is the downstream total pressure and Ve is the exit velocity. At the disk itself the pressure jumps delta p = pte - pt0 Therefore, at the disk, delta p = .5 * r * [Ve ^2 - V0 ^2] WebHence, F = 710 × 9.8 = 6,958N. Thus the minimum force required by the motor to overcome the gravity is F = 6,958N. By applying the power formula, P = F v, the minimum power …

WebThe answer is simple: horsepower is calculated by multiplying the amount of force (in pounds) by the speed (in feet per second). So, let's say your car's engine can generate 200 … Web1. Define effective horsepower (EHP) conceptually and mathematically . 2. State the relationship between velocity and total resistance, and velocity and effective horsepower . 3. Write an equation for total hull resistance as a sum of viscous resistance, wave making resistance and correlation resistance. Explain each of these resistive terms. 4.
The following definitions have been or are widely used: In certain situations it is necessary to distinguish between the various definitions of horsepower and thus a suffix is added: hp(I) for mechanical (or imperial) horsepower, hp(M) for metric horsepower, hp(S) for boiler (or steam) horsepower and hp(E) for electrical horsepower.
