# Help : Fresh concrete frictional drag force

#### tarek.abulail

##### عضو جديد
I need help in determining the force on horizontal pipe length of 3.0m
The pipe is pumping concrete of 2400kg/m3
Pipe diameter is 125mm
Pumping initial pressure is 130Bar = 13000KPa
Concrete velocity 1.0m/hr
Assuming frictional constant is maybe around 0.45 (I need advice on this one)
The pipe is horizontal.
The purpose of these calculations is to design support for the pipe while pumping concrete.
Please if some Engineer can help in this one
Please assume any reasonable other assumption if you need to.

Excuse me because I don’t have Arabic keyboard

Thank you

the geometry of the supports is not the issue please assume anything
i want to confirm the calculation of the forces
Thx for getting back to me

الاحمال لديك ستكون نوعان:
1. وزن الكونكريت مع البايب و يؤثر عموديا على المسند
2.الحمل المتمثل باندفاع الكونكريت في البايب ويؤثر جانبيا المسند

Thank you again but my issue is to calculate the second type of loading

2.الحمل المتمثل باندفاع الكونكريت في البايب ويؤثر جانبيا المسند??

I need proper calculations for the corces
