Dynamic Pressure

Loading author...

Calculate q-bar from velocity and density, then convert that pressure into sea-level equivalent airspeed.

Dynamic pressure

6.125 kPa

6,125.0 Pa / 127.92 psf

Equivalent airspeed

100.00 m/s

194.4 kt at sea-level ISA density

Calculation breakdown

True velocity100.00 m/s
Air density1.2250 kg/m3
Density ratio1.000 x rho0
Load on 1 m26,125.0 N/m2

Q-bar build-up

Velocity dominates the curve through V squared; density shifts the whole curve up or down.

rho/rho0 1.000
