Transcribed Image Text:

An oil flow through a horizontal circular pipe of diameter 50 mm, 500 m long at the rate of 0.19 V/s. The kinematic viscosity and relative density of the oil are 2.5 x 10-6 m²/s and 0.8 respectively. (i) Prove that the flow is laminar flow. (ii) Determine the pressure gradient and wall shear stress.
