Los siguientes c lculos fueron realizados por el programa PSICRO, en
base a las f¢rmulas precedentes. Para m s informaci¢n referirse a la
descripci¢n del psicro o a su listado. Los datos de referencia son de [7]
, [6], [8]
El factor de correcci¢n a la presi¢n de vapor (fs) est en 1.
Las presiones y temperaturas elegidas son las que figuran en la bibliograf¡a y
corresponden a n£meros enteros en unidades inglesas.
La Presi¢n de vapor y la Humedad de saturaci¢n est n en la tabla 2.
El Volumen en 3, la Entalp¡a en 4 y la Entrop¡a en 5.
