(15 pts) A liquid of fixed density ρ and fixed viscosity µ flows steadily from left to right at volume flow rate V & through a horizontal round pipe of inner diameter D as sketched. The flow is fully developed . Piezometer tubes are inserted into the pipe at locations 1 and 2. The liquid rises to column heights HGL 1 and HGL 2 at cross sections 1 and 2 respectively. The vertical tubes are of large enough diameter that surface tension (capillary effects) are negligible. Arbitrary reference datum plane ( z = 0) 2 1 Pipe diameter D HGL 1 L Out In HGL 2 ( a ) Write an expression for Darcy friction factor f for this pipe flow in terms of the given variables. Reduce your expression as far as possible. Note : At this point, it is not known whether the flow in the pipe is laminar or turbulent. : At this point, it is not known whether the flow in the pipe is laminar or turbulent....
