Air Flow Studies Apparatus
Product Code : JA-FMAHLE-9926
The Air Flow Studies Apparatus (SKU JA-FMAHLE-9926) is a floor-standing rig for investigating air flow in a pipe and in a free jet. A centrifugal fan draws air through a long smooth-walled pipe fitted with flow nozzles and pressure tappings, and discharges it as a jet that can be traversed with a Pitot tube. JaincoLab supplies this air flow studies apparatus to mechanical and aeronautical engineering colleges for fluid mechanics practicals.
Specifications
The listed data give a centrifugal fan capacity of 218 l/s at STP, pipe velocities of 0 to 35 m/s in an 80 mm by 2.75 m inlet pipe, 50 mm and 80 mm nozzles, 50 mm and 30 mm orifices, a 600 x 140 mm jet traverse and a 0 to 283 mm H2O manometer.

Experiments on the air flow studies apparatus
The air flow studies apparatus supports a series of pipe and jet experiments on one frame, from pressure gradient and boundary layer growth in a smooth pipe to losses in bends and the spreading of a free air jet, for fluid mechanics laboratories.
- Measuring the pressure gradient along a smooth-walled pipe
- Determining boundary layer growth from velocity profiles at four stations using a traversing Pitot tube
- Comparing pressure losses with a bend or mitred cascade elbow fitted midway along the pipe
- Demonstrating pressure loss and recovery with an orifice plate upstream of the fan
- Investigating the dispersion of a free air jet at different distances from the discharge orifice
Scope of supply and ordering
The listing covers the fan, smooth inlet pipe with pressure tappings, two flow measurement nozzles, flow control damper and jet aperture plate, orifice plate, traversing Pitot tubes, multi-tube inclinable manometer and floor-standing frame. The bend or mitred elbow option is confirmed on the quotation. Accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing are confirmed on each quotation for the number of units and the delivery destination. The apparatus is supplied by JaincoLab singly or as part of complete fluid mechanics laboratories for colleges and tender orders.
Frequently asked questions
What is the fan capacity?
218 l/s at STP, giving pipe velocities from 0 to 35 m/s in the 80 mm inlet pipe.
How is boundary layer growth measured?
By measuring the velocity profile at four stations along the pipe with a traversing Pitot tube.
Can free jet studies be done?
Yes. On the discharge side a Pitot tube is traversed vertically and horizontally over a 600 x 140 mm range from the 30 mm discharge orifice.
