SOLVED:Can the enthalpy values determined from a psychrometric chart at sea level be used at higher elevations?

Q4. Use the psychrometric chart to estimate the relative humidity (% saturation), dew point temperature, specific volume, moisture content, and specific enthalpy for an air-water system with a measured dry bulb temperature equal to 25°C and wet bulb temperature equal to 20°C.Provide your results in a table and sketch your method for calculation on the psychrometric chart attached.

SOLVED:Using the psychrometric chart, Fig. A-9, determine (a) the relative humidity, the humidity ratio, and the specific enthalpy of the mixture, in kJ per kg of dry air, corresponding to dry-bulb and wet-bulb temperatures of 30 and 25^∘ C, respectively. (b) the humidity ratio, mixture specific enthalpy, and wet-bulb temperature corresponding to a dry-bulb temperature of 30^∘ C and 60 % relative humidity. (c) the dew point temperature corresponding to dry-bulb and wet-bulb temperatures of 30 an
