Działanie transformaty jest analogiczne do wykorzystywanego w rozwiązywaniu...
The temperature inside the heat exchanger pipe in a steam boiler was subjected to analysis. Heating of the pipe with and without the scale was considered. A calculation model was presented describing the inverse problem of a geometrical type. It allows determining the thickness of the boiler scale based on the measurements of the temperature inside the pipe and the heat flow density on t he outer...
