Answer #1

Corresponding to Dry bulb temp=10C that is 50 F and 50 % relative humidity the value of enthalpy is 16.2 BTU per pound of the dry air.I have attached Psychrometric chats above and point B is marked where 50 F DBT and 50% Rh intersects.

Note DBT is on horizontal axis in chart, and RH are repersented by curved lines in chart., and enthalpy is present on lefthand side with slanted lines.
