Q$1.$ A cooling system is being designed for use where outdoor air is very dry. The space with a high latent load, $\backslash (\backslash$mathrm$\{$SHF$\}=0\mathrm{.}7\backslash ),$ is to be maintained at $75$ F dry bulb and $50$ percent relative humidity. The total heat gain to the space has been determined to be $\backslash (92,000\backslash$mathrm$\{$Btu$\}/\backslash$mathrm$\{$hr$\}\backslash ).$ Outdoor air at $100$ F dry bulb and $20$ percent relative humidity is to be mixed with return air in a way that it can be cooled to $50$ F $.$ The outdoor air requirement of the occupant is $500$ cfm $.$ The air is then supplied to the space. Sketch the processes on Chart $1$a and compute the volume flow rate of the supply air and required cooling capacity of the cooling coil in tons. $(1$ Ton $=12,000$ Btu$/$hr$)$
