I have some Dwyer equipment and following their instructions I attach a 6"x60" duct to the 6" inlet of my cyclone and measure velocity and static pressure. So when I measure 2" of pressure with only this test duct connected, isn't that pressure drop across the cyclone? If I eliminated the cyclone and just attached the duct to the blower wouldn't the measured pressure be that of the duct and be much lower?
