TABLES
Mesure units
Fluid mechanic



Absolute pressure: Absolute pressure = Gauge Pressure + Atmospheric pressure (Atmospheric pressure at 1,01325 bar, i.e. normal atmospheric pressure on the sea level at 0C).
Boiling point: Temperature of saturated vapour or also of ebullient water under the same pressure.
Specific volume of steam: Volume occupied in m3 by 1 kg of steam
Mass density (or Density) of the steam: Specific mass of the steam in a volume of 1 m3
Specific enthalpy
of liquid water:
Sensible Heat, it is the quantity of heat contained in 1 kg of water according to the selected temperature.
Specific enthalpy of the steam: It is the total heat contained in 1 kg of steam. It is the sum of the enthalpy of the various states, liquid (water) and gas (vapour)
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.
Dynamic viscosity: The viscosity of a fluid characterizes the resistance to the movement of the fluid.
NB: Energy values in kcal/kg are given on a basis of 4.1868 J, values not normally used.
