The following data is given for a hydrostatic thrust beanng. thrust toad \( =500 \mathrm{kN} \), shaft speed \( =720 \mathrm{rpm} \), shaft diameter \( =500 \mathrm{~mm} \), recess diameter \( =300 \mathrm{~mm} \), film thickness \( =0.15 \mathrm{~mm} \), viscosity of iubricant \( =160 \) SUS specific gravity \( =0.86 \). Calculate (i) supply pressure: (i) flow requirement in litres/min: (tii) power loss in pumping: and (iv) frictional power loss. \[ (3+7=10) \]
