I have been doing some fluid questions and got stuck ont he following two;
2) Oil of dynamic viscosity 0.12 Nsm-2 is used to lubricate the space between the plain journal bearing with the shaft. The shaft and bearing are concentric and the space between them is filled with an oil of dynamic viscosity of 0.15Nsm^-2.
Determine the torque required to overcome viscous resistance and the power loss when the shaft is rotating at a speed of 3000rpm.
