Marks: +1, -0

Ambient air is at a pressure of 100 kPa, dry bulb temperature of 30oC and 60% relative humidity. The saturation pressure of water at 30oC is 4.24 kPa. The specific humidity of air (in g\/kg of dry air) is __________ (correct to two decimal places).

Your Answer:

Validate

Solution:

ϕ=\;{p_{v}}/{p_{v s}}

0.6=\;{p_{v}}/{4.24}

p_{v}=2.544

ω =\;{0.622 p_{v}}/{P-p_{v}}

ω \;\; =16.24 \;{\;\text " gram "\;}/{ {kg}}
