Correct option is B
The basic difference between pipe in series and pipe in parallel is given below:
| Pipes in Series |
Pipes in Parallel |
| Pipes are said to be in series if they are connected end to end (in continuation with each other) so that the fluid flows in a continuous line without any branching. |
When two or more pipes are connected the fluid flow splits among the branch pipes and eventually combines at downstream into a single pipe. Such a piping system is referred to as parallel pipes. |
| The discharge will remain the same. |
The discharge will be the sum of the discharges in individual pipes. |
| Total head = Sum of heads of all the pipes connected in series |
Heads will remain the same. |
| The head loss will sum up of head loss in each pipe. |
The head loss in each pipe will be the same |
