Question

consider a room filled with air at 15 deggrees celsius and 75 percent relative humidity calculate the temperature of the windows of the room at which air starts condensing at the inner surface ?

a)10.6 degree celsius
b)11.8degree celcius
c)15 degree celcius
d)12.7 degree celcius

Answer 1

Answer:

Relative humidity (∅) = 75% = 0.75

air temperature is 15 degree C

so based on the table at 15 degree C

P(sat) = 1.7057 kpa

∅ = 0.75 = p(v) / p (sat)

we will get,  

P(v) = 0.75 x 1.7057

P(v) = 1.2793 kpa

temperature value is = 10.6 degree C

Answer 2

Answer:

10.6 degree celcius the answer is
