Q1. An oil of relative density 0.92 and dynamic viscosity 0.082 Pa.sec flows in an 80mm diameter pipe. In a distance of 20 m the flow has a head loss of 2 m. Calculate (i)the mean velocity. (ii) discharge, (iii) velocity and shear stress at a radical distance of38 mm from the pipe axis and (iv) boundary shear stress.

remember velocity variation is not linear. It varies from 0 to umax w.r.t r if you have any doubts…

Oil is being transported at a rate of 20gal/min through a 2-in schedule 40 steel pipe (ID = 2.067in). The oil has a viscosity of 20cP and a specific gravity of 0.85. The line is slanted, and the static pressure at one point in the line is 45 psig. Calculate the static pressure (in psig) at a location in the line 200 feet further along flow direction and 50 feet lower in elevation.
