Pipe Flow Calculations Forum

what way can i use the formula to give me a comparable value to the practical results though?? cheers

i'v done the practical side of things with the pipe in the wind tunnel with air speeds of approx 4m/s, 6m/s and 10m/s entering the pipe, the end of the pipe is going to atmosphere, the exiting speeds are approx 2m/s, 2.5m/s and 4m/s. from my calculations i seem to be getting pressure drops using thi...

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 t...
