More than 5 years have been passed, but it appears that SewerGEMS still ignores the headloss coefficient calculation for pits. I'm using SewerGEMS SS4 08.11.04.54. Is there any newer version that can do this calculation?
Hi Scott,
Thanks for your reply. Actually a pit is a catch basin, I mean.
I was wrong in my previous post saying SewerGEMS ignores headloss coef. calculation. Yes, the software now DOES headloss coefficient calculations, but unfortunately, in the example as attached, it appears that the software does not calculate the headloss (or provides a wrong water surface level in catch basin).
Given the pipe is full flowing, the water surface level in the catch basin would be at least = 30.119+0.3+2.01*2.57*2.57/(2*9.807) = 31.096m assumed the energy slope is equal to the pipe slope, not 30.490 as calculated by the software as shown in attached screenshot.
