0 0 votes The relative humidity of ambient air at $\text{300 K}$ is $50\%$ with a partial pressure of water vapour equal to $p_{v}$. The saturation pressure of water at $\text{300 K}$ is $p_{sat}$. The correct relation for the air-water mixture is $p_{v}=0.5\:p_{sat}$ $p_{v}=p_{sat}$ $p_{v}=0.622\:p_{sat}$ $p_{v}=2\:p_{sat}$ Thermodynamics gateme-2021-set1 thermodynamics fluid-mechanics applied-mechanics-and-design numerical-answers + – ♦gatecse 293 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
