Air Flow Studies

Product Code : JE-MELE-10962

Air Flow Studies
The equipment comprises a long smooth walled pipe connected to the suction side of an electrically driven centrifugal fan. 
Air enters the smooth walled pipe through one of the two flow-measurement nozzles provided.
Pressure measurements are made on a multi-tube inclinable manometer mounted on the support frame.
A conventional flow-measuring orifice plate is supplied for installing in the pipe upstream of the fan for additional demonstrations of pressure loss and recovery. 
Pressure tapings along the length of the pipe permit the pressure gradient to be determined. 
A bend or mitered cascade elbow may be fitted midway along the smooth wall pipe for comparison of pressure losses. 
Boundary layer growth is determined by the measurement of the velocity profile at five stations along the pipe using a traversing Piton tube.
A Piton tube is traversed vertically and horizontally at different distances from the discharge orifice to investigate the dispersion properties. 
Air-jet studies are carried out on the discharge side of the fan. 
The fan discharge pipe terminates in a flow-control damper for closed conduit work or a plate containing a small aperture for jet dispersion measurements. 
The equipment is mounted on a floor-standing steel frame with an adjacent support for the extended suction pipe.
