P= 2πNT/60000 kw,
1kw=1000Nm/sec.
P=πNT/30.
1kw=1000Nm/sec.
P=πNT/30.

But why taken 2π NT/60000.

POWER TRANSMITTED BY SHAFT = 2ΠNT/60 N-M/SEC.
BY SOLVING IT WE GET TΠN/30 N-M/SEC.
BY SOLVING IT WE GET TΠN/30 N-M/SEC.

P = T * w.
where T = Torque and w = angular velocity.
w = 2*π*f.
if we want to express in terms of rpm------> N.
N revolution in 1 minute,
N revolution in 60 sec.
N/60 revolution in 1 sec = f.
So, P = T * 2 * π *N/60 = T * N * π/30.
where T = Torque and w = angular velocity.
w = 2*π*f.
if we want to express in terms of rpm------> N.
N revolution in 1 minute,
N revolution in 60 sec.
N/60 revolution in 1 sec = f.
So, P = T * 2 * π *N/60 = T * N * π/30.
