A fully developed flow of an oil is taking place in a pipe of diameter 300mm. The velocity atthe centre of the pipe is 2.0m/s. Given the specific gravity and dynamic viscosity of the oilflowing to be 0.8 and 2.5×10−3N s/m2respectively. Determine the following:

i Average velocity of water in the pipe.

ii Diameter at which the the velocity of water is equal to the average velocity.

iii Velocity at 30mmand 40mmfrom the wall.iv Reynolds number of the flow.
