Q7. There are many disk in the hydraulic clutch system to transfer energy from driving shaft to driven shaft Some example is shown in the figure below. R1=30 cm, R2=40 cm, h=3 mm, n1=300 rpm, n2 =200 rpm $\mu_{oil}$=0.29 kg/ms $\rho_{oil}$=900 kg/m³. Assuming a linear velocity profile for the oil film, determine the transmitted torque through the system.
