-<u>'''CHOKED FLOW EQUATION''' dimensional units:</u>
-The only difference between the the metric units version and the U.S. customary units version is in these terms:
-Metric: &nbsp; '''Q = A ( <i>p</i> P )<sup>1/2</sup>'''
-U.S.: &nbsp; '''Q = A ( g<sub>c</sub> <i>p</i> P)<sup>1/2</sup>'''
-All of the other terms are dimensionless.
-'''Metric units:'''
-Q = m<sup>2</sup> [ kg/m<sup>3</sup> • kg/(m•s<sup>2</sup>) ]<sup>1/2</sup> = m<sup>2</sup> [ kg<sup>2</sup>/( m<sup>4</sup>•s<sup>2</sup>) ]<sup>1/2</sup> = kg/s &nbsp; &nbsp; &nbsp; &nbsp; Note that P = Pascal = kg/(m•s<sup>2</sup>)
-'''U.S. units:'''
-Q = ft<sup>2</sup> [ ft/s<sup>2</sup> • lb/ft<sup>3</sup> • lb/ft<sup>2</sup> ]<sup>1/2</sup> = ft<sup>2</sup> [ lb<sup>2</sup>/(s<sup>2</sup> • ft<sup>4</sup> ]<sup>1/2</sup> = lb/s
