A lubricating oil of viscosity 1 poise and specific gravity 0.9 is pumped through 

a 30 mm diameter pipe. If the pressure drop per metre length of pipe is `20( kN)/m^2`, determine:

1. The mass flow rate in kg/min,
2.  The shear stress at the pipe wall,
3.  The Reynolds number of flow, and 
4. The power required per 50 m length of the pipe to maintain the flow.

In a pipe of 300 mm diameter, the maximum velocity of flow is found to be 2 m/s. If the flow is laminar,find:the average…
