Hydraflow

Keep getting Error of "no flow".  New to hydraflow, but basically I have two separate storm lines.  The main line has an outflow to a box culvert.  Can't get it working at all. If I enter manually the Q (cfs) value to 0.01, then it will not calculate total capacity.  Also, the HGL seems to be exteremely high and I can't get it down no matter the size of the pipe I enter. Please help. I renamed the file to .doc. to get it to post.

Wouldn't the inlet time be the Tc?

Inlet time =  inlet Tc.

thanks for the quick replies.  If the inlet time is 0, wouldn't it default to the 5 minute minimum anyway?

I just entered valuse in the column for the inlet tc, but I still get the no flow in line....

thanks fcernst! got it working.  Just thought that I could leave the values at 0, and hydraflow would assume the Tc is minimum of 5 minutes.
