Lesson 17. PROBLEMS ON HEAD LOSS
Module 6. Flow through pipes
PROBLEMS ON HEAD LOSS
Q 1. Discharge through a pipe line is 0.05 m3/s. The diameter of pipe at section AB is 10 cm which suddenly changes to 15 cm in section BC. The co-efficient of friction is 0.05 for both the pipes; determine the total head loss from A to C.
Solution
Q = 0.05 m3/s
Q 2. Diameter and length of the different sections of a pipe line is given as follows:
Junctions B and C are cases of sudden contraction & enlargement respectively. If the flow rate is 0.01 m3/s, determine total head loss in entire length of pipe. Contraction loss co-efficient is 0.45.
Junctions B and C are cases of sudden contraction & enlargement respectively. If the flow rate is 0.01 m3/s, determine total head loss in entire length of pipe. Contraction loss co-efficient is 0.45.
Q 3. Diameter & length of different sections of pipe line connected to a large tank given as below. There is an abrupt expansion & contraction at junction B & C. Water is discharged directly into open at end of pipe at D. Determine the height of water surface above the discharge point to get a velocity of 2.5 m/s at the end of pipe. Take contraction loss co-efficient as 0.45.
