In case of pressure driven laminar flow of a Newtonian fluid of viscosity(μ) through a horizontal circular pipe, the velocity of the fluid is proportional to
μ
μ 0.5
μ –1
μ –0.5
Losses for flow through valves and fitting are expressed in terms of
Drag coefficient
Equivalent length of a straight pipe
Shape factor
roughness factor
Water is flowing under laminar conditions in a pipe of length L. If the diameter of the pipe is doubled, for a constant volumetric flow rate, the pressure drop across the pipe
Decreases 2 times
Decreases 16 times
Increases 2 times
Increases 16 times
