An automobile engine develops 100H.P. when rotating at a speed of 1800...
100 HP = 74570 W or 74.57 KW Now, P = 2*π*N*T/60 where, P is the power (in W), N is the operating speed of the engine (in r.p.m.) and T is the Torque (in N.m). Therefore, 74570 = 2*π*1800*T/60 i.e. T = 395.606 N.m

100 HP = 74570 W or 74.57 KW

Now,

P = 2*π*N*T/60

where, P is the power (in W), N is the operating speed of the engine (in r.p.m.) and T is the Torque (in N.m).

Therefore,

74570 = 2*π*1800*T/60

i.e. T = 395.606 N.m
