What is the latent heat capacity of steam?
As the latent heat of steam at atmospheric pressure is 2257 kJ/kg the amount of flash steam produced will be 299/2257 = 0.133 kg/kg of condensate.
What is the latent heat of vaporization of steam?
(1) Latent heat of steam is 540 cal/gm. Express this in SI units.
How do you calculate latent heat of steam?
Latent Heat ( he ) = hg – hf = 2676 – 419 = 2257 KJ / Kg. Cp – Specific Heat of Steam at Constant Pressure, which can be considered as 1.860 KJ/Kg. °C, Ts – Temperature of super heated Steam, Tf – Saturation temperature i.e., 100°C.
What is latent heat of steam at 100 C?
Latent heat of ice = 80 cal/gm. Specific heat of ice =0.5 cal/gm degree ºC. The heat required to convert 10 gm of ice at 20°C into steam at 100°C is – (1) 100 calories (3) 9900 calories (2) 900 calories (4) 7260 calories.
What is the specific heat capacity of steam in J kg C?
1.996 kJ/kgK
The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK.
How do you calculate latent heat of vaporization?
Latent heat calculation The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .
What is the latent heat of vaporization of water in J kg?
For the water substance at 1 atm and 100 °C (the boiling point of water at 1 atm), the latent heat of vaporization is 2.25 ÷ 106 J kg21.
How do you calculate specific volume in steam?
Specific volume is defined as the number of cubic meters occupied by one kilogram of matter….Specific Volume Formulas
- ν = V / m where V is volume and m is mass.
- ν = 1 /ρ = ρ-1 where ρ is density.
- ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity.
How do you calculate latent heat of condensation?
What is the latent heat of steam?
Latent heat of steam is defined as the amount of heat required to change a unit mass of waster from 100 degree Celsius to steam at the same temperature. The latent heat of Vaporization for steam is 2.26 * 106 J kg -1 or 540 Cal g -1.
What is latent heat and specific heat of vaporization?
Latent heat of vaporization: Heat necessary to transform 1 kg of ebullient water into vapour without change of temperature (thermal energy necessary during the change of state liquid to the state vapour). Specific heat of steam : Quantity of heat necessary to increase the temperature of one Celsius degree on a unit of mass of 1 kg of steam.
How much energy does it take to steam at 212 of?
Vacuum steam is the general term used for saturated steam at temperatures below 100°C. At atmospheric pressure – 0 psig – water boils at 212 oF. 180 Btu/lb of energy is required to heat 1 lb of water to saturation temperature 212 oF. Another 970 Btu/lb of energy is required to evaporate the 1 lb of water at 212 oF to steam at 212 oF.
What are the characteristics of saturated steam?
Properties of Saturated Steam – Imperial Units. Steam table with sensible, latent and total heat, and specific volume at different gauge pressures and temperatures. Sensible, latent and total heat in evaporated water – steam – at different gauge pressures and boiling temperatures.
