| THERMAL CONDUCTIVITY OF INSULATING SLABS
|
BY 10260 GUARDED HOT PLATE METHOD
To determine thermal conductivity of specimen,main heater and radial heater sandwitched between copper plates. Specimen in the form of slabs of equal thickness are placed on either sides of heaters and cooling plates. other side of specimen water is circulated. Radial guard heaters ensures all heat of main heater passes axially through the specimen, collected by cooling plates. By knowing the themp. And heat input, thermal conductivity of specimen can be calculated. |
