Hello All I am working on a project where I have to do the hydraulic calculations for 4 buildings. I need to purchase a program to do the calculations. What is the most cost effective yet still user friendly and gives accurate results? I dont need it to be integrated with autocad. Thank you

I am interested of gaining a very in-depth understanding of manual hydraulic calculations for sprinkler design. Can anybody recommend a book what I can purchase that has several examples of different layouts?

Makes sense. Thanks for your reply. Much appreciated.

Hello All I have a question regarding doing the manual hydraulic calculations. I have a case where the area has three identical branch lines and one node on another branch line (which is the most remote). Now when I start from that node and into the cross main, I get a certain Q and a pressure...

Its a corrugated HDPE pipe so we dont have a smooth outer surface for the coupler or buttfusion/electrofusion techniques. The couplers on the inside ace as a bell and spigot type of joint.

Currently using our joining system, for the 200 mm, the diameter is about 188 mm at the joint and then goes back to 200 after the joint. So this is not suitable for sewer? Also, if only for stormwater, we are looking to make the reduction so that the dia becomes 180 approximately. Any problem...

Thanks for the reply. so basically the problem is that sediments could be trapped on the edge of this "hump" if it is large enough. Again, for a 200 mm pipe, what could be this "hump" size that would be just ok?

I forgot to mention. the pipes are HDPE pipes

Hello All We are currently trying to modify the internal couplers on our piping system and one of the solutions is to increase the thickness of the couplers. This will result in a decrease of the pipe OD which will ofcourse have much more effect on the smaller diameters than the larger ones...
