[Problem 6] Psychrometric Chart | How To Read Psychrometry Chart and Solve Numerical by Shubham Kola
Hi every one in today's session we're going to learn about psychometric chart, How To Read Psychrometry Chart (study of air), Problems on Psychrometric chart in Refrigeration & Air conditioning.
Transcript
00:01now for the next numerical
00:02the statement is
00:04with help of psychometric chart
00:05find properties of air
00:07if air is at
00:0824 degree Celsius dry bulb temperature
00:10and 50% relative humidity
00:12find dew point temperature
00:13wet bulb temperature
00:14specific volume of air
00:16enthalpy of air
00:17and specific humidity of air
00:19here we have to plot the process
00:20on psychometric chart
00:22so first we will write down the data
00:24which has been provided
00:25the given data is
00:26air at
00:2724 degree Celsius dry bulb temperature
00:29and 40% relative humidity
00:31and once it is plotted
00:32then we extend this line
00:33we got
00:34dew point temperature as
00:358.7 degree Celsius
00:37and when we extends this
00:39to the right side
00:40the specific humidity we got as
00:410.0065 kilo joule per kg of dry air
00:45and when we saw the specific volume line
00:47then we got some what near to
00:490.85 meter cube per kg
00:50of specific volume
00:52and here the inclined is
00:54specific enthalpy line
00:55In this way
00:56with the help of psychometric chart
00:58we can determine
00:58different properties of air at
01:0024 degree Celsius dry bulb temperature
01:02and 40% relative humidity
