Specific Heat of Air Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-HTL-10047
Jlab Export is a leading Specific Heat of Air Apparatus Manufacturer,and suppliers in India
Specific Heat of Air Apparatus (code EL-HTL-10047) is a flow rig in which a blower drives air over a 1 kW heating coil placed centrally in a test section, for finding the specific heat of air from the heater input, the air flow and the temperature rise. An orifice meter measures the flow and a multichannel digital indicator, reading 0–300 °C, shows the air temperatures. JLab builds the blower, test section and meter panel of this specific heat apparatus in Ambala, India.

The Steady-Flow Energy Balance
Once the outlet temperature is steady, the electrical input goes into heating the moving air: VI = ṁ cp (T2 − T1), so cp = VI/[ṁ(T2 − T1)]. The orifice meter gives the volume flow of air, and multiplying it by the air density at the inlet temperature and room pressure gives the mass flow ṁ. Because the air passes through at almost atmospheric pressure, the value found is the specific heat at constant pressure, cp, the figure used in steady-flow work on ducts and heat exchangers.
Getting a Reliable Value
Some heat escapes through the walls of the test section instead of reaching the air, which makes the calculated cp come out high. Runs at several air flows and heater settings show how large that loss is: at higher flow the temperature rise is smaller, the walls stay cooler and the loss becomes a smaller share of the input. Taking the inlet and outlet readings only after they settle avoids counting heat that is still warming the duct.
