    Dry sump pump issue

    Sounds like a classic case of air entrainment or possibly cavitation if the reservoir isn't feeding the scavenge stage correctly. I've seen similar symptoms when the pickup line wasn't fully primed or had a slight leak. Might be worth checking for aerated oil on return, or verifying that the...

    Engineering task: How prevent metal balls from getting stuck when flowing down and out of a cylindrical container?

    I’ve dealt with this in bulk handling, and the key was adjusting the outlet design. Using a conical hopper with a steeper angle reduced bridging, and adding a small vibration motor kept balls moving. Sometimes a rotating agitator near the outlet helps too. The goal is to maintain constant flow...

    Calculate waterflow on inclined plane

    When I calculated water flow on an inclined surface, I used the Manning equation for open channels—factoring slope, surface roughness, and hydraulic radius. It’s surprisingly accurate even for small-scale setups. Just make sure your measurements are consistent and account for flow width. For...

    Measurement of actual CO2 mass emitted from a diesel engine

    I’ve worked on emission testing setups for diesel engines, and getting accurate CO₂ mass values requires careful integration of exhaust flow rate and concentration data. Using a PEMS unit or combining a flowmeter with an NDIR sensor usually does the trick. Calibration is key. Also, correcting...

    Announcement Official Response to "Allegations of AI misuse in PF"

    I appreciate the transparency in this response. Allegations like this can easily spiral, so having a clear stance on how AI tools are monitored and limited is important. If anything, the real issue is users misrepresenting AI-generated content, not the tech itself. I hope the mods continue to...
