Description

The apparatus consists of blower unit fitted with the test pipe. Nichrome wire heater surrounds the test section. Four Temperature Sensors are embedded on the test section, two placed in the air stream at the entrance and exit of the test section to measure the inlet and outlet air temperature. Test pipe is connected to the delivery side of the blower along with the orifice to measure flow of air through the pipe. Constant heat flux is given to pipe by an electric heater through a variac and measured by Digital Voltmeter and Digital Ammeter.

TECHNICAL DETAILS:

  • Test section: Horizontal, externally heated
  • Diameter : 28 mm (approx.) Length : 400 mm (approx.)
  • Blower: FHP of Standard make
  • Heater: Nichrome Wire
  • Air Flow measurement: Orifice meter & Manometer.

Control panel comprising of:

  • Digital Voltmeter: 0-300 Volt
  • Digital Ammeter: 0-2 Amp
  • Variac : 0-230 V, 2 Amp
  • Digital Tem. Indicator: 0-3000C, with multi-channel switch
  • Temperature Sensors: RTD PT-100 type
  • With standard make on off switch, Mains Indicator etc.

Instruction Manual: An ENGLISH instruction manual will be provided along with the Apparatus
A good quality painted rigid MS Structure is provided to support all the parts

EXPERIMENTATION:

  • To determine average surface heat transfer coefficient for a pipe by forced convection.
