Given: Diameter of pipe, D=5 cm=0.05 m
Flowrate of water, Q=6 L/s=0.006 m3/s
Total length of pipe, L=Horizontal length+Vertical length= 80m+9m=89 m
Elevation at point 2, z2 =4 m
Loss coefficient for sharp edged entrance, KL, entrance=0.5
Loss coefficient for standard flanged elbow, KL, elbow =0.3
Loss coefficient for gate valve (fully open), KL, valve =0.2
Loss coefficient for exit, KL, exit =1.06
- Steady state and incompressible flow.
- There are no pumps or turbines included in the system. Thus loss due to turbine or pump is neglected.
- The elevations remain constant.
Both the points is open to atmosphere, thus the pressure is P1=P2=Patm. The velocity of fluid at point 1 and 2, V1=V2=0.
The energy equation for the control volume system is
