railway RRB JE (CBT I + CBT II) Mock Test 2024 Fluid Mechanics Laminar Flow Laminar Flow through Pipe
A 10 cm diameter straight pipe is laid at a uniform downgrade and flow rate is maintained such that velocity head in the pipe is 0.5 m. If the pressure in the pipe is observed to be uniform along the length when the down slope of the pipe is 1 in 10, then what is the friction factor for the pipe?
