A centrifugal pump is used to supply a highly viscous fluid to a chemical plant. The chemical plant is located at a height of 20 m from the pumping station level. The flow rate required to be pumped is 0.005 m3 /s. The pipe diameter used for pumping is 30 cm and the total length of the pipeline is 50 m. The pipe exits to atmospheric conditions. Compute the Reynolds number and determine whether the flow is laminar or turbulent. Determine the pressure that should be delivered by the pump at its exit in order to maintain the flow. Also compute the power input for the pump assuming a pump efficiency of 100 %. Take the viscosity of the fluid to be 0.01Pa.s. Take the density of the fluid to be 1500 Kg/m3 .

Question

A centrifugal pump is used to supply a highly viscous fluid to a chemical plant. The chemical
plant is located at a height of 20 m from the pumping station level. The flow rate required to
be pumped is 0.005 m3

/s. The pipe diameter used for pumping is 30 cm and the total length of
the pipeline is 50 m. The pipe exits to atmospheric conditions. Compute the Reynolds number
and determine whether the flow is laminar or turbulent. Determine the pressure that should be
delivered by the pump at its exit in order to maintain the flow. Also compute the power input
for the pump assuming a pump efficiency of 100 %. Take the viscosity of the fluid to be
0.01Pa.s. Take the density of the fluid to be 1500 Kg/m3
