Natural Convection Apparatus
Product Code : EL-HTL-11083
The Natural Convection Apparatus from Lab Exports lets students determine the overall heat transfer coefficient for natural convection from a heated vertical brass pipe, using an enclosure to ensure undisturbed convection currents.
Specifications
| Pipe | Brass, 38 mm OD, 500 mm long, with internal cartridge heater |
| Thermocouples | 7 nos., along the length of the pipe |
| Enclosure | 200 x 200 x 800 mm, one side fitted with Perspex sheet |
| Control | Dimmerstat for heater input control |
| Measurement | Voltmeter and ammeter for heater input; multichannel digital temperature indicator |
| Services Required | 230V, 5A AC supply with earthing; bench area 1.5m x 0.75m at working height |
Key Features
- Vertical brass pipe heated internally by a cartridge heater, losing heat by natural convection
- Enclosed in a chamber with a Perspex viewing side to ensure undisturbed convection currents
- 7 thermocouples measure local temperature at points along the pipe
- Voltmeter and ammeter directly measure heater input power
- Allows calculation of overall heat transfer coefficient at various heat rates
- Dimmerstat control enables testing across a range of heat input levels
Applications
The Natural Convection Apparatus is used in heat transfer laboratories to study free (natural) convection from a vertical heated cylinder, helping students determine the overall heat transfer coefficient at different heat transfer rates and compare results with theoretical correlations.

Frequently Asked Questions
Q1. What does the Natural Convection Apparatus measure?
It measures the overall heat transfer coefficient for natural convection from a heated vertical brass pipe at different heat transfer rates.
Q2. Why is the pipe enclosed?
The pipe is enclosed in a chamber to prevent air disturbances and ensure undisturbed, purely natural convection currents.
Q3. How is temperature measured along the pipe?
7 thermocouples fitted along the pipe length feed a multichannel digital temperature indicator.
Q4. How is heater input measured?
A voltmeter and ammeter measure the electrical input to the internal cartridge heater, controlled by a dimmerstat.
Q5. What utilities are required to operate the apparatus?
It requires a 230V, 5A AC supply with earthing connection and a bench area of approximately 1.5m x 0.75m.
