The following plot gives the saturated humidity (He) versus temperature (T).Line joining (H1, T1) and (H2, T2) is the constant enthalpy line. Choose the correct one from among the alternatives A, B, C and D____________________?
Correct answer: D
Explanation
The constant enthalpy line connects the dry bulb temperature (T1), wet bulb temperature (T2), and dew point temperature (T3) in that order.
