Question

Two different system x and y have same specific enthalpy. System 'x' has dry bulb temperature of ${28}^{\circ }C$ and relative humidity of 57.4%. System 'y' has a relative humidity of 33.%. What can be its dry bulb temperature?

• A. ${22}^{\circ }C$
• B. ${28}^{\circ }C$
• C. ${35}^{\circ }C$
• D. ${25}^{\circ }C$

Answer 1

The correct option is C ${35}^{\circ }C$


DBT at 33.1% should be greater than DBT at 57.4%. Since both x and y have same specific enthalpy therefore same WET so only 'B' option (${35}^{\circ }C$) can be a solution of the given problem from the options.
