Thank you. I will try to upgrade entire line to 12" hdpe. The current configuration has all HDPE SDR 11 on both 12" and 8" pipes.

thanks again for trying to help. The current configuration does 1100gpm and i was asked to determine what line size should we upgrade the line for it to achieve 1750gpm. Other than that, the material properties that i gave all are what i received. Please let me know what additional information...

Also, just found t=out that we need to consider froth factor due to air line content in the line. froth factor of 1.25 can be considered

S.G 1.13

i was told density is same as % solids, the viscosity is similar to water. The highest flow we have seen on that flowmeter is 1100gpm

sorry if i am confusing with word selection. Basically, what I am trying to determine is whether the current configuration is capable of handling 1750gpm or not. If not, what should be the size of upgraded line to handle 1750gpm.

this shows 8" converting to 12" before discharginghttps://files.engineering.com/getfile.aspx?folder=ce79614b-0e28-4d6b-9124-f679c6f013ca&file=MicrosoftTeams-image_(1).png

this picture shows path of 8" (ignore vent line thing)

this pictures shows 12" line reducing to 8"https://files.engineering.com/getfile.aspx?folder=d3d86d57-2788-4ac1-9d88-a480e12eb47b&file=12inch_to_8inch.jpg

This line shows 12" coming from bottom of that distributor boxhttps://files.engineering.com/getfile.aspx?folder=2b7a19d7-b26e-4fba-90d0-b18d0f334fea&file=5.jpg

Hi, Currently no idea about viscosity, for now could you consider some value, say The distributor is just a normal one, the total length of that box is 10' and it is half filled The elevation at the start and end point of the 8 inch is 3732'-1" and 3721' - 1" Does this help to do flowrate...

Hi Everyone, I have a HDPE pipeline carrying slurry which has % solids of 20-25% and specific gravity 1.13. The pipeline starts off as a 12" line, then reduces to 8" for majority of path and finally before discharging into a thickener it becomes 12" again. The elevation difference between first...

Thanks for all the replies, appreciate it. And thanks for being more patient in responding to my half baked question. I just got started so i am still learning. The picture does not show complete pipeline but shows major part of the 8" line, however the elevation difference from beginning to end...

The way I calculated head is Head = density x g x height = 0.15 * 9.81 * 11 = 16.18’ (sorry i mentioned 32' previously) i considered density as 0.15 because %solids are 15% (is it right ?) i have uploaded picture of the 8" pipeline i was referring...

the elevation difference is 11'

I have a 8" gravity feed line sized to handle 1359gpm flow (% solids is 15% and sg 1.13). Total length of this line is almost 100ft. I calculated the total head in the line to be 32'. I would like to increase the flow in the line by installing a vent pipe in the line as i believe there are some...
