the present invention relates to the system which can cool an electric power tunnel efficiently through the fact that the temperature of a cooling water does not change for a certain period due to phase change between the ice and the water in the cooling water, using the latent heat which is...
Related to latent heat:Latent heat of fusion,Latent heat of vaporization latent heat n. The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also calledheat of transformatio...
known mass of water at a room temperature T 1 . The heat required to melt the ice will be supplied by the water. After the ice cube melts, by measuring the temperature change of the water, we can calculate the quantity of heat exchanged between the water and the ice. When the heat ...
更新1: sorry~ i kg should be 1 kg Heat required to melt all the 0.5 kg ice = 0.5 x 334 kJ = 167 kJ where 334 kJ/kg is the specific latent heat of fusion of ice. Heat given out by the 1 kg water when its temperature drops to 0 deg.C = 1 x 4200 x 20 J...
heat necessary to change 1 g of liquid to vapor (latent heat of vaporization) without change of temperature; heat necessary for change of state being negative or positive heat (e.g., fusion, evaporation, and melting). For example, the latent heat of fusion of ice water is 80 cal/g...
The latent heat flux, Fl, is the exchange of energy between the surface and the atmosphere that occurs when water is evaporated from or condenses onto the surface. From: Encyclopedia of Atmospheric Sciences, 2003 About this pageSet alert ...
[translate] aIn the first phase, the latent heat of vaporization heats up the rock, oil, and irreducible water in the chamber. 在第一个阶段,潜在汽化热在房间加热岩石,上油和不能降低的水。[translate]
To find the final temperature of the mixture when 100 g of ice at 0°C is mixed with 100 g of water at 80°C, we can use the principle of conservation of energy. The heat lost by the water will be equal to the heat gained by the ice.1.

Since main heat source is external supply of steam in most pharmaceutical enterprises and the water cann't be used as additional water of boiler, this paper proposes a steam condensate latent heat and water recycling system which not only take full advantage of the heat of the steam condensing...
