Psychrometric chart geometry: shape of constant wet-bulb temperature lines. Evaluate the statement: “On a standard psychrometric chart, the wet-bulb temperature lines are curved lines.” Decide whether the statement is true or false.

ConceptOn standard psychrometric charts, lines of constant wet-bulb temperature are drawn as straight oblique lines (nearly coincident with lines of constant enthalpy). Relative humidity lines are the curved family.

Final AnswerDisagree (false).
