Instructor: Mr. The document describes an experiment to study heat transfer Type of flow: forced and free convection When the flow of gas or liquid comes from differences in density and temperature, it is called free or natural convection. The document summarizes an experiment on heat transfer from heated surfaces via free and forced convection. It begins by outlining the objectives of understanding the physical The heat transfer would be different for free and forced convection therefore Heat losses must be determined separately. forced or assisted convection; natural or free convection; Conductive Heat Transfer; Forced or Assisted Convection. 4 Introduction forced convection - Download as a PDF or view online for free.
