Dear All

I am trying to determine / estimate the expected air velocity and pressure at the end of a 5m long hose, supplied by a centrifugal fan coupled directly onto the hose. The information / assumptions i have are;

Fan System

Static Pressure: 4kPa

Volumetric Flow: 40m3/min

Pipe

Length: 5m

Diameter: 110mm

Roughness: 0.05mm

Minor Loss Coef: 0.1

Air

Temp: 15°c

Density: 1.1 kg/m3

Kinematic Viscosity: 10 E-6 m2/s

From this is it possible to estimate the velocity of the air stream at the start of the hose and at the and (v1 & v2) and the associated pressures (p1 & p2)? If it is ,what are the calculations?

I assume that due to the resistance caused by the pipe there will exist a 'back pressure' in the pipe. What would this pressure be 1m from the fan outlet (1m down the pipe).

Thanks
