Mollier-Diagram Calculator and Sketcher This diagram is widely used in mechanical engineering and HVAC technology and plots the Temperature versus the Absolute Humidity. The chart is is combined with the Relative Humidity lines and the Enthalpy to calculate the change in total internal energy. The Psychrometric Chart is also known as the "Mollier-Diagram". PDF The Pressure - Enthalpy Chart - Parker Hannifin the water temperature vs. the enthalpy of the water (heat con-tent in Btu/lb). We all know that water boils at 212ºF (atmos-pheric pressure at sea level). By definition, water at atmospher-ic pressure, at a temperature lower than 212ºF, is subcooled. So, we start with subcooled water at 42ºF, and begin transfer-ring heat to it. en.wikipedia.org › wiki › Phase_(matter)Phase (matter) - Wikipedia This unusual feature of water is related to ice having a lower density than liquid water. Increasing the pressure drives the water into the higher density phase, which causes melting. Another interesting though not unusual feature of the phase diagram is the point where the solid–liquid phase line meets the liquid–gas phase line.

A P-h diagram can be constructed for any pure substance.Like the P-n diagram, there are regions on a P-h diagram in which two phases exist together. PDF Pressure-enthalpy Charts and Their Use - Rses In refrigeration service work, gauge pressure (psig) is generally used. On a pressure-enthalpy diagram, however, the pressure is shown as absolute pressure (psia.) The difference between the two is about 14.7 pounds per square inch or about 30 inches of mercury (29.92 inches of mercury, to be more precise).
