Constrained Convection Apparatus The Forced Convection Apparatus is intended to decide warm move rate in constrained convection. It comprises of even copper tube warmed by an electric radiator. Number of thermocouples are fitted on the surface of the tube along its length. The test pipe is housed inside a steel pipe. A blower gives constrained convection of air by blowing the air at high speed to cause turbulent stream. Stream rate of blower is estimated by hole plate & U Tube Manometer.The control board comprises of a dimmers detail to control the voltage provided to the warming component. A Voltmeter, an ammeter and a computerized temperature pointer are likewise given. Particulars: Test Pipe: Copper Pipe, Diameter 30 mm, Length of Pipe 500 mm Electric Heater: Capacity 300 W, Supply 230 V AC Air Blower: Centrifugal Blower, 230 V AC Orifice Plate: For Air Flow estimation Manometer: U tube manometer, 0-300 mm WC Dimmer: Range 0-250 V AC, 2 A Digital Voltmeter: Range 0-500 V AC Digital Ammeter: Range 0-2 An AC Temperature Sensors: Type ‘K’ Thermocouples – 12 Nos Temperature Indicator: 12 Channel Indicator with Selector Switch, Range 0-199.9 ° Frame: Made of M.S. Square Tubes & Sheets, Welded & Powder covered Experimental Capabilities: To think about wonder of Heat Transfer in Forced Convection To decide the Heat Transfer Coefficient (h) in Forced Convection Comparison of trial comes about with hypothetical qualities .
