Project file: Head Loss here
In MiTS software, we are using Hazen-Williams Equation as shown below to calculate the head loss.

Online Head Loss Calculator #
- We also test the value given in our software with an online head loss calculator.
- You may click here for the online head loss calculator.
- Node 1 is taken as an example, please refer image below:

- As you can see that the result generated from MiTS software is equivalent to the one calculated by the online head loss calculator.
- Velocity = 0.3883 m/s
- Head Loss = 0.2040 m
Manual Calculation #
- We used formula below to calculate the head loss with known Discharge, Q (m3/s), Pipe Diameter, D (m), Pipe Length, L (m) and Hazen-William Coefficient, k of the material used.

- As the Q is known, we will need to rearrange the equation to find the value of V.

- After obtaining the value for V, we will rearrange the Hazen-William Equation to get the value for S.
