V = sqrt( ( 2 * pressure * nozzle_area ) / water_density )

I plug in the values for my water rocket to get

V = sqrt( ( 2 * 17.24newtons/cm

^{2}* 3.80 cm

^{2}) / 1 gram/cm

^{3})

After some simplification:

V = sqrt( 131 newtons * cm

^{2}/ 1 gram )

That does not look anything like a velocity. How do I get the terms to work our correctly?
