CAT NO: DIDACTICHeat Equipments0006
Heat Transfer In Forced Convection.
Heat Transfer In Forced Convection
The apparatus consists of Blower unit fitted with the test pipe.
Nichrome wire heater surrounds the test section
Sensors are embedded on the test section, two placed in the air stream
at the entrance and exit of the test section to measure the inlet and
outlet air temperature. Test pipe is connected to the delivery side of
the blower along with the Orifice to measure flow of air through the
pipe. Constant heat flux is given to pipe by an electric heater through a
variac and measured by Digital Voltmeter and Digital Ammeter.
To determine average surface heat transfer coefficient for a pipe losing heat by forced convection.
Comparison of heat transfer coefficient for different airflow rates and heat flow rates.
To plot surface temperature distribution along the length of pipe
Electricity Supply: 1 Phase, 220 V AC, 10Amp.
Floor area of 1.2mx 0.5m
