(b) Water flows under gravity between two reservoirs through a pipe of length 5000m. The diameter of the pipe is 0.2 m and the roughness size is 0.04 mm. The water levels in the two reservoirs are maintained with a difference of 50 m. Determine the discharge through the pipe. Neglect all minor losses. Use the attached Moody diagram for estimation of friction factor. (10 marks) (c) In (b), now include entry loss at the upper reservoir with loss coefficient...

EDIT: The fluid in the system is water. There is no data
regarding the inclination of the pipe. It's known that the
equipment used includes a fluid flow piping system (AFT), hydraulic
bench (FME00), barometer, and psychrometer. Also added an appendix
that has recommended equations.
