Forced Convection Apparatus

Forced Convection Apparatus

Forced Convection Apparatus: Scientific Equipment

• The LABAPPARA unit consists of mainly a centrifugal blower, electrically heated test section, control valve to regulate the airflow and an orifice-meter and U-tube water manometer for flow measurement.
• Thermocouples are used to measure the pipe wall temperature and also the air temperature at inlet and exit.
• The apparatus mainly designed to find out the value of heat transfer coefficient under the air different conditions.

Feature

• Heat transfer in forced convection can be studied well.
• The value of heat transfer coefficient is calculated under various fluid flow conditions.
• Ideal for group studies & demonstration.
• Test pipe – 32mm NB GI pipe, 500 mm. long, heated by band heater, outside.
• Centrifugal blower to force air through test pipe with How control valve.
• Variac 2A, capacity to force air through test pipe with flow control valve.
• An orifice meter with differential water manometer.
• Voltmeter and Ammeter to measure heater input.
• Multichannel digital temperature indicator to measures various temperatures.
• A technical manual accompanies the unit.
