4. Head loss :- Head loss is potential energy that is converted to kinetic energy. Head losses are due to the frictional resistance of the piping system (pipe, valves, fittings, entrance, and exit losses). Unlike velocity head, friction head cannot be ignored in system calculations Introduction

5. Minor losses Major losses Losses in pipes

6. Major losses

7. Major losses  are associated with frictional  energy loss  that is caused by the viscous effects of the medium and roughness of the  pipe  wall.

8. Frictional loss

9. The fluid flowing in the pipe is always subjected to resistance due to shear forces between fluid particles and the boundary wall of the pipe and between the fluid particles themselves resulting from the viscosity of the fluid. This resistance to the flow is called frictional resistance and loss of head due to that is called frictional losses.

10. Laws of fluid friction

11.   LAWS OF FLUID FRICTIONAL FOR LAMINAR FLOW. LAWS OF FLUID FRICTIONAL FOR TURBULENT FLOW Laws ( i ) (ii)

12. LAWS OF FLUID FRICTIONAL FOR LAMINAR FLOW. The frictional resistance in the laminar flow is – proportional to the velocity of flow . independent of the pressure . proportional to the surface area in contact. independent of the nature of surface is contact.

13. LAWS OF FLUID FRICTIONAL FOR TURBULENT FLOW The frictional resistance in the case of turbulent flow is – proportional to (velocity). independent of pressure . proportional to the density of the flowing fluid. proportional to the surface area in contact.
