A frustum$-$shaped body is rotating at a constant angular speed of $200ra\frac{d}{s}$ in a container filled with SAE $10W$ oil at Pa$-$s$),$ as shown in the figure. If the thickness of the oil film on all sides is $12mm,$ determine the power required to maintain this motion Also determine the reduction in the required power when the oil temperature rises to $-$s$).$

The power required to maintain this motion is

w

The reduction in the required power input when the oil temperature is raised to $80C$ is

w$.$
