Question 38
CHMCQ2 marksNeeds review
Vapor pressure of water at various temperature is given in the table.
Temperature (in K) | 284 | 289 | 294 | 299 | 310 |
|---|---|---|---|---|---|
Vapor pressure of water (in kPa) | 1.28 | 1.80 | 2.50 | 3.40 | 6.40 |
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 mol
and specific heat capacity of the air and water vapor mixture is 0.035 kJ mol
K
. Which one of the following is the closest to its wet-bulb temperature (in K)?Your answerChoose one option.
