HEAT TRANSFER IN FORCED CONVECTION APPARATUS

Product Description

Technical Description:

The apparatus consists of blowerunit fitted with the test pipe.

Nichrome wire heater surroundsthe test section. Four Temperature Sensors are embedded in the test section,two placed in the air stream at the entrance and exit of the test section tomeasure the inlet and outlet air temperature.

Test pipe is connected to thedelivery side of the blower along with the orifice to measure the flow of airthrough the pipe.

Constant heat flux is given topipe by an electric heater through a variac and measured by Digital Voltmeterand Digital Ammeter.

Learning Objectives/Experiments:

To determine average surface heattransfer coefficient for a pipe by forced convection.

Comparison of heat transfercoefficient for different airflow rates and heat flow rates.

To plot surface temperaturedistribution along the length of pipe.
