Vapor pressure of water at various temperature is given in the table.
An air and water vapor mixture at 100 kPa with a relative humidity of 20% has a dry-bulb temperature of 310 K. Assume latent heat of vaporization for water is 44 kJ molβˆ’1 and specific heat capacity of the air and water vapor mixture is 0.035 kJ molβˆ’1Kβˆ’1. Which one of the following is the closest to its wet-bulb temperature (in K)?
A
284
B
294
C
310
D
321

Correct : b
