The apparatus consists of a circular pipe, loosing heat by forced convection to the air being forced through it. Constant heat flux is added to the pipe by an electrical heater, provided with input control. The pipe surface temperature is measured by thermocouples at various points along the length of pipe. Temperatures of air inlet and outlet of test sections are measured. Thus the students can calculate local and overall heat transfer coefficients in forced convection, at various air flow rates and various temperatures. Specifications: Test Pipe - 32 mm G.I.Pipe, 500 mm long, heated by band Heater. Centrifugal Blower to force air through test pipe with flow control valve. An Orifice meter with differential manometer to measure air flow rate. Instrumentation & Controls : Multy channel Digital Temperature Indicator. Digital Voltmeter - 0 - 199.9 Volts. Digital Ammeter - 0 - 1.99 Amp. Heater Control. Service Required : 230 V.A.C. stabilized supply with earthing. Floor space - 1.5m X 1.5 m approx.
