## Minor Loss

#### 2. Loss due to sudden Conraction

##### v2 is the velocity in the contracted region.
Case 1 & 2 are between pipe to pipe

#### 4. Loss of head at the Exit of Pipe

Case 3 & 4 are between pipe & tank

##### Now we will calculate the losses when we are combining pipes

Pipes can be combined in series, parallel or both.

### 1) Pipes in series

Note: As the pipe are in series, the discharge through each pipe will be same

### 2) Pipes in parallel

Note: As the pipe are in parallel, the discharge through each pipe will be sum of discharge through main pipe

Loss of head in each pipe will be same in parallel

### 3)Equivalent Pipe

A compound pipe which consists of several pipes of different lengths and diameters to be replaces by one equivalent pipe having uniform diameter and same length is known as equivalent pipe or in other words single pipe representing combination of pipes.
