Specific enthalpy of moist air

WebSpecific heat of moist air relative humidity between 0 and 100%. Source publication +7 Study of thermophysical properties of a solar desalination system using solar energy Article Full-text... WebThe annual average temperature across the state ranges from around 39 °F (4 °C) over the Adirondack Mountains to near 53 °F (12 °C) across the Hudson Valley and Long Island, to around 56 °F (13 °C) within New York City. Weather in New York is heavily influenced by two air masses: a warm, humid one from the southwest and a cold, dry one from the northwest.
