Pipe Loss App

This is a Python App built with Kivy Library which computes the head loss of a fluid moving along a pipeline system taking into account Major and minor losses.

🔰 How does it work?

This app is based in Kivy builder. It has several windows where an user could input the data to compute the head losses of a fluid into a pipe system with accesories.

Main Window

There are 3 windows where an user could input the data:

• Fluid Properties
• Pipe Characteristics
• Accesories

And there is a button to compute the head loss.

Fluid Properties

In this window an user must input the flow rate in $\frac{m^3}{s}$, and select the fluid in order to load its density $(\frac{kg}{m^3})$ and dynamic viscosity $(Pa-s)$. By default, an user could select any of the following fluids:

• Water
• Air
• Glycerine
• Oil
• Gasoline

But there is an Other option which open another window where the user could input data such as:

• Name of the fluid
• Density
• Dynamic Viscosity

Pipe Characteristics

In this window an user must input the length of the pipe $(m)$. After that, it's necessary to set the Material Roughness and the Geometry Section

Material Roughness

There is a list of default materials with its roughness $(m)$. But the user could select Other Material option in order to input the data for a specific pipe material.

Geometry Section

In this window there are 4 option of cross section for the pipe:

• Circular

• Annular Circular

• Rectangular

• Annular Rectangular

If the user selects any of the geometries a new window appears where is possible input the geometry data.

Accessories

In this window the user must select the type of inlet (connection with a tank)

• No inlet
• Inward-projecting
• Sqaure-edged
• Chamfered

Also it's necessary to define whether there is an outlet or not using the switch

Finally, the Accessories Button shows a window with a list a common accessories in pipeline systems such as valves, elbows etc. An user just need to enter the number of each accesory in the pipeline system. By default, all accessories have a value of 0.

Example

This is the solution of the problem 11.7 from the book Applied Fluid Mechanics, 7th by Mott R. and Untener J.
