WebMunters PsychroApp psychrometric calculator lets you easily calculate the thermodynamic properties of moist air more accurately than using psychrometric charts. Calculate the total, sensible, latent and moisture loads of any process. Munters PsychroApp provides quick and easy access to calculations such as dew point and grams per kilogram. WebFrom this intersection, the remaining three air properties can be read from the chart. Both the dew-point and humidity-ratio lines are horizontal and the values are shown on the right side of the chart. In this example, the humidity ratio is about 118 grains of moisture per pound of dry air and the dew-point temperature is approximately 72°F. WebThe constant value WB and H lines on the psychrometric chart are the same. If the Dew Point (DP) is known then the Humidity Ratio (W) is known (and vice versa) and a second condition is not required. The constant value DP and W lines on the psychrometric chart are the same. At 100% RH, DB = WB = DP. DP is calculated from DB and WB. first pair free coastal
