CALLENDER AND BARNE’S CONTINUES FLOW CALORIMETER

CALLENDER AND BARNE’S CONTINUOES FLOW CALORIMETER – Physics Equipment

Callender and Barnes’ Apparatus also known as Continuous Flow Calorimeter is a scientific instrument that is designed to find the specific heat capacities. The apparatus consists of a horizontal corning glass tube open at both ends. The heating element is a coil about 40 cm long of Ni-chrome wire and is wound spirally inside the axis of the glass tube. The complete apparatus is mounted on a polished wooden base board. 

  • For determining the specific heat of water or similar liquids.
  • Consists of a glass tube 100 mm long with heating element (electric wire).
  • Two screw terminals are provided at the ends of the tube for electric supply.
  • The horizontal tube is connected by means of rubber bungs to the inlet & outlet system.
  • Each having a vertical expansion to accommodate the thermometer.
  • A stream of water is made to flow through the glass tube & heated by the spiral by passing electric current.
  • With the help of an adjustable constant boil tank, the rate of flow is kept constant.
  • The rise in temperature of water is measured by two thermometers
  • Supplied with thermometer.
  • The Apparatus consists of glass tube carrying inside a spiral of wire.
  • A Steam of water is made to flow through the glass tube and heated by the spiral by passing electric current.
  • The whole apparatus is fitted on a polished wooden board.
  • Complete with constant level tank with thermometers.
