Calculated result

49.393 N·m torque

Torque: 49.393 N·m (36.43 lb·ft)

Shaft power: 7.5 kW (10.058 hp)

Speed: 1,450 rpm

Angular speed: 151.844 rad/s

This is a steady operating-point shaft relationship, not starting, breakdown or locked-rotor torque.

  1. 1. ω = 2π × 1,450 ÷ 60 = 151.843645 rad/s.
  2. 2. P = T × ω = 49.392913 × 151.843645 = 7,500 W.
  3. 3. T = 7,500 ÷ 151.843645 = 49.392913 N·m.
