2π*N*T/4500,
10π.

1 kg = 9.81N.

Power = angular velocity x torque x 9.81 watts.

Power = 2πNT/60 ( in watts) = 2πNT/(60*746) (in HP).

N = 150 r.p.m.
T = 150 Kgm = 150*10Nm = 1500Nm (1kg = 10N approx).

After putting all value in the equation you will get,
Ans : 10π.

Work done per second = 2πNT/60KNm.
N=RPM.
T=Torque in KNm.

2πNT/45000.
Because 1hp =746watt.
Then you will get 10π.

P = 2πNT/60.

P = 2*π*150*150*10/60*746watt.
= 10π.

@Venkat.

T is in kg-m, so convert it to Newton by multiplying 10m/s^2.
You will get 4500.

P = 2πNT/4500.
We get p=31.41,
Which is equal to 10π.
