equation: P = r * V2/2,
where P stands for pressure and is measured in pa (pascals), r stands
for density and is measured in kg/m3, and V stands for
velocity and is measured in m/s.
Replace the variables with the correct unit; ignore constants.
Change derived units to fundamental units.
= kg/m3 * (m/s)2 ----------- (pa = n/A)
* m/s2)/m2 = kg/m3 * ( m/s)2
------------- (n = kg * m/s2 and A = m2)
Perform the indicated binary operations.
* s2) = kg/(m * s2)
