    Compressor Station Cleaning, Testing, & Purging

    I am putting together a procedure for cleaning and testing (hydro and pneumatic testing) a newly installed natural gas compressor station, but I'm having trouble finding good resources to help. Can anyone point me in the right direction?

    B31.3 and Gathering Pipelines

    Good Morning Forum, Would any experts out there be able to explain to me if gas gathering lines (moving gas from wells to the gas processing plant) are included in the scope of B31.3 (maybe as "compressor interstage piping")? Or would these be covered under B31.8 (gas gathering pipelines)...

    Smaller dt Hint Message

    We're trying to replicate the work done in an older version of HydroCAD using version 9.00. We are getting message 49 "Hint: Tc<2dt may require smaller dt" for one of our subcatchments. The Tc is 5.8 minutes. Our dt was set at 0.50, which we reduced to 0.10, but the message remains. What do...

    TURN.LSP Issues

    I just downloaded Turn117.lsp and ran the lisp a few times with my WB67 block. However, each time I run the lisp, the program only draws the path of the midpoint of the rear axle. I watched the YouTube video on how to run the program and saw that the lisp is supposed to generate a whole lot...

    CHECKRAS

    I am trying to use CHECKRAS v1.4 for the first time, but I am having trouble extracting the data from my HEC-RAS report. I am following FEMA's CHECKRAS tutorial and I've deleted and regenerated the HEC-RAS report a few times over. I keep getting an error message when I click the "Extract"...

    Import/Export Hydrographs

    Can anyone explain to me how I can best export a hydrograph from one HydroCAD file and import it into another HydroCAD file? I want to import a hydrograph as a link node, which requires me to have a .hce file, but I don't have that option on the export end. I would rather not have to manually...

    Catch Basins

    I was wondering if someone could clear something up for us here regarding the use of catch basins in HydroCAD... Are there any benefits to modeling catch basins as separate nodes from an upstream detention pond? I ran a test on a simple stormwater system and found that my flows and WSEs are...

    Supercritical/Critical/Subcritical

    Hello All, I am attempting to model the floodway of a ditch in HEC-RAS, but am having trouble with varying output. When I model the system using subcritical or mixed flow regime, the resulting WSEs are much higher than when I use the supercritical flow regime. Can anyone please define...

    Baffle Design

    I have several detention basins with forebays on site that will be utilized as sediment basins during construction. I want to use baffles (essentially rows of silt fence to elongate the flow path) in place of the forebay berms for erosion control. Does anyone know if there is some sort of...

    Diagram Labels

    Is there any way to change the font size on cross-sectional diagrams? I have a reach node that shows a cross section in the report, but the labels are so large, they are overlapping each other. If it is not possible to reduce the font size, is there a way to get rid of the labels?

    Sub-Driveway Infiltration Bed

    I'm designing an infiltration area below a large, looped driveway area so that the post-developed 10-year flow will equal the pre-developed 2-year flow. I am placing two inlets in the driveway area so stormwater can flow into the infiltration bed more quickly, rather than just seeping through...

    Print Diagram

    I imported a .wmf file as my diagram background and now want to print the routing diagram WITH the picture in the background. Each time I try to print the diagram, I only get the nodes (no background). How can I print both from HydroCAD. Is this even possible?

    HydroCAD multistage outlet

    I am using HydroCAD to model a catch basin with two inlets and two outlets and am having trouble figuring out how to go about it. The two inlets are a rectangular orifice to control the flow of the 10-year storm and a top grate to allow the 25-,50-, and 100-year storms to enter the catch basin...
