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: $Q=A(\rho P)^{1/2}$

U.S.: $Q=A(g_{c}\rho P)^{1/2}$

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
