Grosvenor Humidity Chart
In 2004 we celebrated the 100th anniversary of Willis H. Carriers hygrometric chart. Four years later, we celebrate the centennial of the humidity chart produced by William Mason Grosvenor Jr., a chemical engineer of New York City. Both charts are now known as psychrometric charts in most of the world and as Mollier h-x charts in parts of Europe.Units: I-PCitation: ASHRAE Journal, vol. 50, no. 10, October 2008
