Message No. 16833, Started by engrilyas on 10/03/05
I am faced with the task of studying a flour milling plant as part of my industrial project.The plant operates on pneumatic transport system with air blowers(fans) placed at different points to supply air at high speeds for the process.I am required to show wheather the fans used have powers adequate for the installed capacity of the plant.

To do this,I need to know the pressure drop in this multiphase system.How do i get this?Is there any way i can calculate an equivalent 'diameter' for the pipe whose diameter changes progressively over its entire length? please help
