A thick walled glass shell with 2 baffles contains cold water, which passes over 7 stainless steel tubes through which hot water flows. Tube bundle length of 205mm giving total heat transfer area of approximately 24000 mm2. Four thermocouples measure hot and cold fluid entry and exit temperatures. Self sealing quick release connections enable rapid connection to the exchanger and conversion from parallel to counter-current flow.
It is a self-contained incorporated a combined compressor and vacuum pump, allowing investigation both above and below atmospheric pressure.
Instrumentation includes gas pressure, volume and temperature allowing the investigation of the characteristic gas equation pV=mRT by more advanced students.
Experiment capabilities :
- Demonstration of Boyle’s Law pv = Constant for air and other safe gases.
- Investigation of the characteristic equation of a gas pV = mRT at ambient temperature.
A bench mounted panel with integral electrical console providing services for any of the optional heat exchangers in the range. Temperature controlled hot water is provided and the hot and cold flow is controlled and measured using variable area flowmeters.
The optional heat exchangers are connected using non-drip, self sealing couplings. Standard instrumentation consists of up to 12 thermocouples, a digital panel meter, and two flowmeters.
