###### Question:

5. A gear pump supplies oil at the rate of 0.85 m'/min and produces a pressure increase of 0.8 bar. The speed of the pump (N) is 2000 rpm. The area (a) enelosed between two gears is 2.5 cm2, axial length (L) of the teeth is 3 cm and the total number of teeth (n) are 25. Determine the volumetric efficiency of the pump ( Given: Theoretical disharge aLnN 60
