84. Problem 18.39 (RHK) Liquid mercury (viscosity, |
Solution: Click For PDF Version (a) In order to find whether the flow is laminar we will calculate the Reynolds number
Internal radius of the pipe is 1.88 cm and the volume flux is
Speed of flow of mercury in the pipe
Reynolds number for this speed of flow is
As this is less than 2000, flow is laminar. (b) Volume flux through a pipe of length L and radius r is
Difference in pressure between the two ends of the pipe is
