Flow through a Bend Appratus

Flow through a Bend Appratus .

Description of Flow through a Bend Appratus:

The module consists of two parts, a straight section Followed by a regular 90 ° elbow. The lower and lower are made of black acrylic plastic while the Sides are transparent. The conduit measures 60 mm Height for 50 mm depth.Several measuring points are located both in the partsThe top and bottom of the elbow joint to Connection with multi-tube manometer,device Necessary for the use of this module. The appliance is designed for use on the basic air flow bench and connected by pipes Twisted to the experimental duct 'blown' at the exit of the fan. However, it can be used separately in Connecting to a suitable fan an air flow of about 500 liter / sec for 600 Pa and using the manometer Multitube of DIDAC The velocity of the air is measured by a Pitot tube, supplied With the bench, connected to the double pipe manometer inclined. Curves representing typical results Can be obtained are presented in the graph cidessus.

Experimental Ability of Flow through a Bend Appratus:

1. Study of the flow around the elbow fitting.
2. Theoretical test on the effects of the boundary layer,Turbulence and on a single whirlwind.
3. Calculation of the volumetric flow around the elbow ratio.
4. Calculation of the Bernoulli equation between the upstream sector Duct and any point in the reportelbow.
5. Definition of the dimensionless pressure coefficient.
6. Comparison with theory and actual readings of Pressure coefficients as well as the pressure loss at Through the elbow.

Functionalities of Flow through a Bend Appratus:

1. Consists in studying the distribution of pressure along of the inner and outer walls of a duct Rectangular shape.
2. Coupled to an elbow fitting with many points of static pressure on the two inner walls and Outside.
3. Several measuring points on the side of the wall Immediately connected to the front of the elbow report.
4. Transparent acrylic conduit for observation of air flow
5. Static pitot tube mounted in a rectilinear duct
