The Mollier diagram shown in Fig. 4 contains 10 curves for relative humidity from 10% to 100% (saturation curve). Page 5 of 15 1 (877) 91-FASTI From the examples shown in Fig.5, we can clearly see that the dew point of the air is directly related to the moisture content of the air.
The Mollier diagram is a very useful instrument to solve HVAC-problems graphically. It includes all humidity functions in one chart. Fig. 4a : Mollier diagram: curves of constant relative humidity . The region below 100% (fog region) is not
Based on Mollier diagram and ethylene mass flows, refrigeration capacity of the system is calculated when some changes in the cargo economizer are done. Some of these changes are carried out by crew members of gas carriers in order to reduce second stage discharge temperatures of ...
Compression Process in a Mollier Diagram for Methane. The compressor head (H) can be determined from the suction and discharge pressure and temperature, assuming the gas composition is known. The compressor is usually assumed to be an adiabatic
The Mollier diagram is used only when quality is greater than 50% and for superheated steam. Steam Tables. Steam tables consist of two sets of tables of the energy transfer properties of water and steam: saturated steam tables and superheated steam tables.

The diagram below right shows the thermal changes on a Mollier diagram for a typical ejector using high pressure steam as the motivating fluid and saturated vapor as the suction fluid. Ejector Efficiency There are many accepted formulae to express ejector efficiency.
condition at bellow saturated line of Mollier diagram, named condensing turbine. If steam condition exit the turbine in dry or still in superheated condition or at upper of saturated line of Mollier diagram, named back pressure turbine, see figure 7.
This can be shown graphically in a Mollier diagram. A Mollier diagram is a graph which reflects the situation of air. And from which we can read by means of the temperature and the absolute moisture content the relative humidity. A couple items are given.
