HEAT TRANSFER BY NATURAL AND FORCED CONVECTION
The DL DKT032s module is a desktop equipment that is designed for the study of heat transfer by natural or forced convection.
The system operation involves the passing air through a duct heated using heating elements with different geometric surfaces. In order to allow the study of forced convection, the system is supplied with a suitable.
The equipment includes also a computer.
