    Measuring Back Pressure Without an Engine

    here we go: "The mass flow rate is primarily dependent on the cross-sectional area A of the hole and the upstream pressure P"

    Measuring Back Pressure Without an Engine

    Yes, this would be sampling not 100% testing. Although buying an engine might be the easiest and most accurate testing, it wouldn't be very time efficient for a quality lab or the cleanest method for testing parts that are still going to be sold. The manager of this project wants compressed air...

    Measuring Back Pressure Without an Engine

    The back-pressure testing is not yet required by Chrysler, this is just planning ahead for when it is required so Chrysler is going to be left out of the discussion for the moment. 850 mbar represents a new, clean system and 1100 mbar represents an aged system with ash and soot accumulated...

    Measuring Back Pressure Without an Engine

    Yeah Mike, 3-4 HP seems about right for 900 kg/hr of air flow thanks. 850 mbar of backpressure does seem quite high but hey I'm not going to question Chrysler's specs. The engine's actual exhaust temperature is 450 degrees Celsius. Does there need to be some sort of conversion of numbers...

    Measuring Back Pressure Without an Engine

    Yeah true, I will give the facility I belive there might be higher voltage outlets. I wonder how much mass flow a 1 or 2 HP motor can create? We have to measure parts from certain batches before they leave the plant to make sure they are within the backpressure specifications. There is the...

    Measuring Back Pressure Without an Engine

    Thanks Mike! Yeah I'm going to get some precise pressure guages. This testing is going to be inside a facility and is going to be happening many times a week, so a blower that regulary trips a breaker would not be sufficient since we'll be working off of 110 V outlet. You said you did some...

    Measuring Back Pressure Without an Engine

    There are many techniques on how to measure backpressure in an exhaust system that is already connected to an engine. How can you measure the backpressure in an exhaust system if it is not going to be connected to one though? What could you use to represent the airflow and backpressure to...
