Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I have used an orifice for my project to measure the pressure difference and hence the mass flow rate of air going through a pipe of 26 mm diameter. i kept changing the flow from max to min and ended up with values of pressure diference. The questions here is how to convert thses values ( in meters) into mass flow rate (kg/s) ?? I tried to find equations for this but they have the coefficient of discharge involved and i cannot find this value !! can any one help me on this plz ?

regards
