9a. A circular pipeline in horizontal position (1) $400\mathrm{mm})$ of length 2640 it carries water at the rate of $2.40{\mathrm{m}}^3/\min$. Compute the Reynoles No of flow. head loss due to friction and velocity at the centreline of the pipe. Take kincmatic viscosity of water as 0.018 stokes and the pipe is smooth. (or) 9b. Determine the Reynolds No of tlow, centruine velocity and head loss due to Inction at the two ends of a circular pipe in horizontal pisition of diameter $100\mathrm{mm}$ and length $10^3\mathrm{cm}$ when 100kg of crude oil flows through the pije in 30 seconds. The oil if of viscosity 0.97 poise and relative density 0.90 . The pipe is smot th.
