$($c$)$ In an electrically heated chamber, $300m^3$ of moist air is heated to $313K.$ The initial conditions of the air are as follows :

'Dry' bulb temperature $=303K$

Wet bulb temperature $=298K$

Pressure $=101\mathrm{.}325$KPa

Determine the

$($i$)$ Amount of Sensible heat added

$($ii$)$ Final relative humidity

$($iii$)$ Final Wet bulb temperature

$($Use Psychrometric chart$)$
