How do you find the Enthalpy of a steam table?

T = Saturation point of steam/water (boiling point) vf = Specific volume of saturated water (liquid). vg = Specific volume of saturated steam (gas). hf = Specific enthalpy of saturated water (energy required to heat water from 0°C (32°F) to the boiling point)

What is the Enthalpy of dry steam at pressure of 5 bar?

Take specific heat of water as 4■ 187 kJ/kg K. From steam tables, at 5 bar, h = 640-23 KJ/kg and L – 2,108 5 kJ/kg. Enthalpy of 1 Kg of wet steam at 5 bar and 0-9 dry above O’C, H*e\ = h + xL = 640 23 + 0-9 x 2,108-5 * 2,537-88 KJ/Kg.

What is the Enthalpy of saturated steam?

2676 kJ/kg
Specific Enthalpy of Saturated Steam For saturated steam at standard atmosphere – 2) – the specific enthalpy – hg – is 2676 kJ/kg.

What is the vapor pressure of steam?

The triple point of H2O, where the three phases of ice, water and steam are in equilibrium, occurs at a temperature of 273.16 K and an absolute pressure of 0.006 112 bar. This pressure is very close to a perfect vacuum.

What is effect of increase of pressure on the enthalpy of steam?

The higher the pressure of a boiler the more heat must be applied to make steam. With the increased pressure, you in turn get steam at higher temperatures. Higher temperature steam contains more energy per pound, which is known as Enthalpy.

What is difference between superheated steam and saturated steam?

Superheated steam is created by further heating wet or saturated steam beyond the saturated steam point. This yields steam that has a higher temperature and lower density than saturated steam at the same pressure.

What is effect of increase of pressure on the Enthalpy of steam?

How to calculate the specific enthalpy of steam?

Specific evaporation enthalpy for water at standard atmosphere is: The energy to evaporate 5 kg of water at atmospheric pressure can be calculated as The specific enthalpy of superheated steam can be calculated from: cps = 1.860 (kJ/kg oC) at standard atmosphere. Be aware that cps varies with temperature.

Which is the bubble on the pressure enthalpy chart?

The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition.

What are the properties of saturated steam pressure?

Properties of Saturated Steam – Pressure in Bar Saturated Steam Table with properties like boiling point, specific volume, density, specific enthalpy, specific heat and latent heat of vaporization

What is the pressure of a steam gauge?
