internal energy of less than 1 kJ/kg Explanation: (Note my confidence level is not high). Although the units kJ/kg can indeed measure "heat capacity", in this case I suspect they are talking about the properties of a gas or other substance, specifically its 'energy density' or internal energy. |

| portata calorifero inferiore kJ/kg heater capacity lower than kJ/kg Explanation: k = 1000 è sempre minuscolo (es. km, kg) e qui si scrive kJ e non Kj; mi sono permesso di correggere la domanda [PDF] AS ASHFormato file: PDF/Adobe Acrobat Electric heater capacity. iiPotenza termica con batteria ad acqua ... col 50% di umidità relativa) è 49,8 kJ/kg, per cui il punto ... www.novema.no/novema/06\splitt\iasuw.pdf - Pagine simili -------------------------------------------------- Note added at 6 hrs (2007-04-05 06:52:01 GMT) -------------------------------------------------- calorifero is a heating element; while "potere calorifico inferiore" è il calore specifico (=per unità di massa) che un fluido può cedere Gas naturale - WikipediaPotere calorifico superiore: 13284 kcal/kg oppure 9530 kcal/Nm3; Potere calorifico inferiore: 11946 kcal/kg oppure 8570 kcal/Nm3 ... it.wikipedia.org/wiki/Gas_naturale - 56k - Copia cache - Pagine simili Ricordo che 1 kcal = 4,1868 kJ -------------------------------------------------- Note added at 8 hrs (2007-04-05 08:09:57 GMT) -------------------------------------------------- Qualora si parlasse del potere calorfico (o calorifero) di un combustibile in inglese è: p. calorifico superiore = gross or higher heating value p. calorifico inferiore = net or lower heating value vedi riferimento sotto http://te-webserver.cce.iastate.edu/courses/ce525/Combustion... The heat (enthalpy) released in combustion, or heating value, is an important parameter in solid waste combustion. The energy produced will be consumed in heating the feed and product gases and lost to the surroundings through the walls of the incinerator. Heats of combustion or heating values are determined using bomb calorimetry. The sample is burned in pure oxygen in an enclosed volume and the energy given off is measured as the temperature increase of the bomb and its surroundings. The measured heat released is the “gross or higher heating value” because condensed water is formed in the calorimeter. The “net or lower heating value” corresponds to combustion conditions producing water in the vapor state. |
