Water has a specific heat capacity of 4182 J/kg°C.Because water is such an important and common substance, we even have a special way to identify the amount of energy it takes to raise one gram of water by one degree Celsius—a Calorie. This is different from the kind of calorie we ...
/h), (c) : specific heat of water (kcal/kg*°C), R: a circulating water quantity of cooling water (m3/h), Q: latent heat of evaporation of water (kcal/kg), N : concentration power (times) of cooling water, and the theoretical replenishing water quantity (M) may adopt a ...
Assuming that 50% of the heat is useful, ow many kg of water at 15∘C can be heated to 95∘C by burning 200 litre of methane at STP ? The heat of combustion of methane is 211kcal/mol. Specific heat of water is 1.0kcalkg−1K−1. View Solution The heat of combustion of ...
cp = specific heat of water (kJ/kgoC, Btu/lb oF) (4.2 kJ/kgoC, 1 Btu/lbmoF for water) dt = temperature difference between the hot water and the surroundings (oC, oF)) m = mass of water (kg, lbm) Example - Energy stored in a 1000 liter water tank Water is heated to 90oC....
Five hundred kcal of heat is added to 2 kg of water at 80 degrees C. How much steam is produced? Latent Heat of Vaporization The heat required by an object to get converted from solid-state to the liquid state at a constant temperature ( or at the b...
temperature by unit degree is known as the specific heat of that substance. Different substances have different values of the specific heat. The unit to express the specific heat is {eq}\rm J/kg \cdot K {/eq}. The specific heat of the water is {eq}4186 \ \...
