Shaft (250 mm diameter) rotates at 250 rpm inside a sleeve (251 mm diameter)
with a constant clearance. If the power required to rotate the shaft is 2204 watts,
find the viscosity (N.sec/m) of lubricant oil in the clearance. Take length of
sleeve as 150 mm.
Your answer
A shaft with a 25 mm radius is pushed at 300 mm/s inside a 25.5 mm radius bearing sleeve with a 230 mm length. Between them, a 0.003m2/s - kinematic viscosity oil has been poured to fill the space. It has a specific gravity of 0.8. How much force does the oil exert on the shaft?
