  • Leak Rate Units - Leak Test Systems | Leak Testing

    The leak test industry in the U.S. has standardized on stating leak rates in units of "scc/m" or "scc/s" (atm cc/s) – standard cubic centimeters per minute or second. European industry uses "Pa-m3 /s" or "mbarl/s.". These are the SI gas leakage rate units defined in the Nondestructive Testing Handbook, Second Edition.

  • WHAT PRESSURE RADIATOR CAP RATING SHOULD I USE? – …

    We get asked this question daily and it seems most people misunderstand what the pressure cap does. The cap pressure rating has nothing to do with regulating your engine coolant temperature, nor will it make your engine run cooler. Let's take a pan of water and heat it up. The water heats up and boils and 212 degrees. Now let's take a pressure cooker and do the same thing. The water will

  • Dumb Question on hydraulic pressure - Page 3

    Nov 09, 2017 · There is a tremendous difference in the flow rate but not the pressure. Some have noted that to lift a maximum load some tractors will need a higher RPM. This is because of "leaks" in the system have to be overcome by more flow so that pressure can be developed by the restriction of a cylinder. Again, pumps make no pressure, they just make flow.
