| Asolute pressure: |
Absolute pressure = Gauge Pressure
+ Atmospheric pressure (Atmospheric pressure at 1,01325 bar,
i.e. normal atmospheric pressure on the sea level at 0°C). |
| Asolute pressure
of vaporization: |
Temperature of saturated vapor or
also ebullient water under the same pressure. |
| Density of water: |
Ratio of the mass of water
(kg) occupied in a volume of 1 m3. |
Specific enthalpy
of liquid water: |
Sensible Heat, it is the
quantity of heat contained in 1 kg of boiling water according
to the selected temperature. |
| Specific heat of liquid water: |
Quantity of heat necessary to increase the temperature
of a 1° Celsius per unit of mass of 1 kg of water. |
| Volume heat capacity
: |
Quantity of heat necessary to increase
the temperature of a 1° Celsius on a unit of volume of 1 m3
of water. |
| 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.
NB : To obtain overheated water, the operating pressure
must be obligatorily higher than the vaporization pressure
according to the selected temperature.
