Steam Nozzle Performance Apparatus with Compressor
Product Code : EL-TELE-10715
Steam Nozzle Performance Apparatus with Compressor (code EL-TELE-10715) is an experimental unit for studying a nozzle as a producer of kinetic energy or thrust, and the way the inlet-outlet pressure ratio governs mass flow and pressure distribution in the nozzle. It works on compressed air supplied from a laboratory source, with quick-change convergent and convergent-divergent nozzles, axial pressure tappings connected to 8 panel-mounted pressure gauges, and instrumentation for pressure, mass flow, temperature, thrust and impact force.

What Is the Steam Nozzle Performance Apparatus with Compressor Used For?
A nozzle converts the pressure energy of a flowing gas into kinetic energy, and the reaction of the jet leaving it produces thrust; the mass flowing depends on the ratio of inlet to back pressure until the nozzle chokes. Students fit a convergent or convergent-divergent nozzle in the measuring chamber, adjust the regulator for the inlet pressure and the backpressure valve for the outlet pressure, and read the axial pressure tappings on the 8 gauges along with mass flow, temperature, thrust and impact force. From these results they show choking, compare measured mass flow with theory, and calculate nozzle efficiency, jet velocity, jet reaction and specific thrust over a wide range of pressure ratios.
What to Specify When Ordering
- Quantity — the number of nozzle units required.
- Power supply — 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase.
Frequently Asked Questions
What can students study with this unit?
They examine a nozzle working as a kinetic energy or thrust producer and see how the ratio of inlet to outlet pressure affects mass flow and the pressure along the nozzle.
What working fluid does the unit use?
The unit runs on compressed air from a laboratory source; a pressure regulator, throttle valve and backpressure valve vary the airflow rate and the inlet and back pressures.
Which nozzles are available?
Convergent and convergent-divergent nozzles are available, each designed for a different theoretical expansion ratio, and they can be changed rapidly in one of two locations in the measuring chamber.
How is the pressure distribution measured?
Each nozzle has axial pressure tappings that connect to the 8 pressure gauges mounted on the panel, giving the pressure at points along the nozzle.
What quantities does the instrumentation record?
The unit measures pressure, mass flow, temperature, thrust and impact force, so jet reaction, specific thrust, jet velocity and nozzle efficiencies can be worked out.
Does the unit show nozzle choking?
Yes. Nozzle choking is demonstrated visually, and measured mass flow rates are compared with theoretical values over a wide range of pressure ratios.
