velocity to pressure??

hi all, newbie here!!
i'm writing a report for college in which im investigating the effect of roughness on air flow through a pipe. so far i have used 2 pipes in a wind tunnel, 1 rough and 1 smooth bore, 800mm long with a 36mm inner diameter. using an anemometer i measured the wind speed entering the pipe and exiting the pipe, this gave me the change in speed. my calculations on the other hand have given me a change in pressure (D'Arcy Weisbach eqn) is there any way i can convert between the change in pressure and the change in air speed?? thanks for any help
