Heat Transfer From A Pin-fin

Heat Transfer From A Pin-fin The setup is designed to study the heat transfer in a pin fin. It consists of pin type fin fitted in a duct. A fan is provided on one side of duct to conduct experiments under forced draft conditions. Air flow rates can be varied. A heater heats one end of fin and heat flows to another end. Heat input to the heater is given through Variac. Digital voltmeter and digital ammeter are provided for heat measurement. Digital Temperature Indicator measures temperature distribution along the fin.  EXPERIMENTATION:    To study temperature distribution along the length of fin in both Free & forced convection.   Comparison of theoretical temperature distribution with that of experimentally obtained distribution.  UTILITIES REQUIRED :    Electricity Supply: 1 Phase, 220 V AC, 5 Amp.  Table for set-up support.  TECHNICAL DETAILS :    Fin                           :                    Pin type.   Material                   :                    Brass.   Size                         :                    12.5 mm (approx.) 15 cm. long (approx.).   Duct                         :                    Made of MS.   Fan                          :                    Standard make.   Heater                     :                     Band type, Nichrome Wire.   Dimmerstat              :                    0-230 V, 2 Amp.   Digital Temp.
