CHOKED FLOW EQUATION dimensional units:
The only difference between the the metric units version and the U.S. customary units version is in these terms:
Metric:
U.S.:
All of the other terms are dimensionless.
Metric units:
Q = m2 [ kg / m3 • kg / (m•s2) ]1/2 = m2 [ kg2 / ( m4•s2) ]1/2 = kg / s
U.S. units:
Q = ft2 [ ft / s2 • lb / ft3 • lb / ft2 ]1/2
