The frequency of the propeller of the aircraft is 1500 rpm, how many revolutions does the propeller make on the way of 90 km at a speed of 180 km / h.
To determine the number of revolutions made by the propeller of the aircraft, we use the formula: ν = N / t, whence we express: N = ν * t = ν * S / V.
The values of the variables: ν is the rotational speed of the screw (ν = 1500 rpm = 90 * 10 ^ 3 rpm); S – aircraft path (S = 90 km); V – speed (V = 180 km / h).
Calculation: N = ν * S / V = 90 * 10 ^ 3 * 90/180 = 45 * 10 ^ 3 revolutions.
Answer: The propeller of a given aircraft will make 45 * 10 ^ 3 revolutions on the way.
