How to make Design Calculation/Perhitungan Pressure Drop Line Air/Udara

            Assalamualaikum Warahmatullahi Wabarakatuh

This time I will also share the Design Calculation of the Pressure Drop Air Line, for selection of Compressor Air models (Requirment Compressor Air).

In this article I will give an example of calculating the manual, not using software but using Excel that I have created. Please later download Excel and fill in all the data written in red only, and everything is automatically calculated and the results also appear.

For example in this calculation I use Project based data that I have worked on (Kawasaki Gas Turbine complete with HRSG BOILER.

Because of the project, I need an Air Instrument (for all Pneumatic Cintrol Valve) and Water Seal (for Purging and Staratup Gas Turbines).

So Please Read the Steap by Steap :

     1.     This Drawing in the below, example conversion from m3/h to Nm3/h : 

     2.  Please input your data in the column (Block Red Color) :

     3.    Please input your data in the column (Block red color) : (for Viscosity table you can see in the side right complate with Reynold Number for input data in the coolumn Friction), input requirment pressure GasTurbin and data Press. Drop in Filter.

     4.    So you can see drawing in the below regarding result calculation (block green)

please download ecxel calc. in the below :

-       Excel Pressure Drop

-       Table Lenght Equivalent

-       Grafik Moody (Renold Number)

If there is something wrong in the design calculation, i'm Sorry, becoause I still need to study a lot in the world of Engineering.

Hopefully this article can provide benefits, Regards and the success.
