Determination of Friction Coefficient of pipe of various diameters
1. Darcy’s friction varies from 0.0005 to 0.01 for pipes.
2. Headloss due to friction in pipe can be reduced by:
3. Liquid flows through a horizontal pipe having diameter 100 mm (friction factor = 0.05) with a velocity of 4.0 m/s. The pipe length is 100 m. What is the head loss due to friction?
4. Friction factor when the flow becomes fully turbulent
5. Friction factor is function of for rough pipes.
6. If flow velocity is doubled, then the frictional head loss becomes:
7. For laminar flow in pipe of uniform diameter, the relation between Darcy’s friction factor and Reynold’s number is:
8. Darcy friction factor for Laminar flow is based on:
9. Moody’s diagram is used to calculate in pipes.
10. Assumptions of Poiseuille’s Law:
