Specific heat also known as specific heat capacity is a thermodynamic concept that is responsible for measuring and quantifying the amount of heat that is required to be administered to a unit of mass of a thermodynamic system to raise a unit of temperature. In this way, due to th...
cp = specific heat of water (kJ/kgoC, Btu/lboF) (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 90 oC....
/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 corrected...
Step 1: Calculate the heat lost by the waterThe first step is to calculate the heat lost by the 5 kg of water when it cools down from 20°C to 0°C. Using the formula:Q=m⋅c⋅ΔT Where:- m = mass of water = 5 kg- c = specific heat of water = 1 kcal/kg°C- ΔT ...
Water has high specific heat. The specific heat is the amount of caloric energy per unit mass needed to increase the temperature of a substance by 1 °C. The high specific heat of water (1 Kcal/Kg °C = 4180 J/kg.K), attributed to its capacity to store energy in ...
fusion: 330 kJ.kg -1 (or 79 kcal.kg -1 ) and for vaporization: 2250 kJ.kg -1 (or 539 kcal.kg - 1 ) at normal pressure and at 100°C. Owing to the substantial amount of specific heat and latent heat of vaporization, the large expanses of water ...
