What is the Velocity of the pumped air in an EDF?

I am using an E-Flite DeltaV 15 EDF on 3S Lipo and it Absorbs 300 Watts from the Lipo. E-Flite says the velocity of the air in the tailpipe is 71 mph.

Is there a mathematical method of calculating the exhaust velocity from knowing the Watts and the density of air? Is another factor needed?

The density of air is 1.29 gms per liter.
