A viscous clutch as shown in figure tranmits torque. Radius of each clutch plate is R and separation between the plates is a and is completely filled with liquid of coefficient of viscous `mu`. If `omega_(i)` and `omega_(0)` are angular velocities of plates connected to input and output respectively. The torque transmitted is
