3. Elastic properties of the liquid flowing through the pipe and pipe material
4. All of these
All of these
1. Pressure gradient remains through all the pipes
2. Hydraulic gradient remains same through all pipes
3. Head loss is same through each pipe
4. Head losses through each pipe are added to obtain the total head loss
Head losses through each pipe are added to obtain the total head loss
1. Smoothen the flow of water
2. Minimize friction losses in pipe
3. Prevent occurrence of hydraulic jump
4. Relieve pressure due to water hamm
Minimize friction losses in pipe
1. At normal depth
2. Above normal depth
