What is S.I unit of calorific value?
The gross calorific value of a substance is the number of heat units that are liberated when a unit weight of that substance is burned in oxygen, and the residual materials are oxygen, carbon dioxide, sulphur dioxide, nitrogen, water, and ash. The energy content of biological materials has been expressed traditionally in calories (c) or kilocalories (C) per gram dry weight. Sometimes results are expressed more significantly in terms of ash-free dry weight, i.e. in terms of organic constituents only. Contemporary studies of ecological energetics express results in terms of the SI energy unit, the joule (4,182 J = 1 calorie).
MORR IS THE CALORIFIC VALUE..MOERRR THE SUBSTANCE PRODUCES HEAT....S.I. UNIT OF CALORIFIC VALUE IS--JOULE(J)..LIK--BIOGAS HS MORR CALORIFIC VALURE THAN WOOD..MEANZ IT PRODUCES MUCH MOR HEAT THAN WOOD..!!
CALO.VALUE..IS A MAJOR DETERMINANT IN SELECTING A FRIENDLY N ECONOMICALLY VIABLE FUEL....:):)
