Torque Formula for Roller Conveyor

F (N) = mu x N (N)
T (Nm)= F (N) x R (m)
Power (W) = F (N) x V (m/s)

From Engineers Edge I got a formula like T = Wk^2 X Change in speed

308t

Wk^2 = W X ( V/2Pi()N)^2

Wk^2 - Inertia of load in lb

V - velocity in fpm

N - Rotational RPM

t - Acceleration time in sec

Can I use the above said formula to calculate the torque , Kind provide technical support to me on this issue
