Forced Convection Apparatus

We are putting forth an extensive variety of Pin Fin In Natural/Forced Convection Apparatus. The exploratory set up comprises a metal bar, one end of which is warmed by an electric radiator while the opposite end of the bar extends inside the cooling water coat. A tube-shaped shell loaded with protecting material encompasses the center bit of the bar. The temperature of the bar is estimated at various areas. Warmth Input to the warmer is given through variac. By differing the warmth input rates, information can be gotten. Water at a steady rate is circled through the coat and its stream rate and temperature rise are noted.

This apparatus is used to calculate the heat transfer coefficient of vertical pin in natural convection / forced convection.

Experimental set up consisting of :

• Vertical pin of dia 12and 125mm long fitted on a heater.
