The air is cooled from $27Cdb$ and $19\mathrm{.}5C$ wb until it is saturated at $13C.$ Using psychrometric chart, find

$($a$)$ the moisture removed per kg of dry air,

$($b$)$ the latent heat removed to condense the moisture,

$($c$)$ the sensible heat removed, and

$($d$)$ the total amount of heat removed $($neglect the enthalpy of the condensed water$)$
