$($Determination of psychrometric properties$)$ Determine the following psychrometric properties of a moist air sample having a dry$-$bulb temperature $27C$ and a humidity of dry air$)$ using the psychrometric chart and$/$or the vapour pressure equation for water:

$($a$)$ relative humidity

$($b$)$ dew point

$($c$)$ adiabatic saturation temperature

$($d$)$ wet$-$bulb temperature

$($e$)$ enthalpy

$($f$)$ humid volume

$($g$)$ humid heat

The Antoine equation for water is $ln{P}_A^v(\frac{?}{\text{b}\text{a}\text{r}})=11\mathrm{.}96481-\frac{3984\mathrm{.}923}{T-39\mathrm{.}724}.$ The total pressure is $1$ atm.
