Friction factor coefficient app for iPhone and iPad

When the pipe transports liquid, a certain amount of pressure is required at one end of the pipe to drive the liquid. The pressure value needs to be calculated according to the drag coefficient, and the drag coefficient will be different due to the different transmission medium, pipe material, and pipe diameter, which causes great trouble to the construction personnel.

The app is used to calculate the drag coefficient of the liquid in the pipe, which can help the builder to get the job done faster.

How to use:
1) Click "Startup" to go directly to the APP homepage.
2) Select the appropriate calculation formula according to your needs. The formulas you can choose are:
"Arit Suri formula", "Nicholas formula", "Shiflinson formula", "Modi formula".
3) Fill in the parameters required for the calculation, such as: "Equivalent roughness", "Tube diameter".
4) Click [Calculation] to get the calculation result: "Friction factor coefficient".


Tips: you can review the calculation history repeatedly in the History.
