Case of the Calorimeter with a Cylindrical Sample

The equation of transient heat conduction through the cylindrical cross-section of the sample, even if the calorimeter is maintained isothermal, is expressed as follows  

The heat flux at the rubber-calorimeter interface is given by  

The assumption in the calorimeter calculation is that the partial enthalpy evolved up to time t, as a fraction of the total enthalpy evolved, represents the conversion up to time t. The overall rate of cure is given by  

2 Case of the Calorimeter with a Horizontal Sensible Detector, Plane in Shape 

The heat flux evolved from the rubber surface to the sensor surface is sanewhat similar to that for the cylindrical sample, with the difference that this flux is expressed lineaiiy
