Based on your lab experiment on the air conditioning bench, assume the air entered the system at $30C$ DBT and $50\%RH$ and came out at $14C$ DBT and $90\%RH.(10$ mark$)$

a$)$ What is the name of the process for such a change in the air properties? $(2$ mark$)$

b$)$ Sketch the process lines on a psychrometric chart and find $h_1,h_2,$ and ADP. $(3$ mark$)$

c$)$ Determine the bypass factor of the coil. $(2$ mark$)$

d$)$ What is the sensible heat factor $($SHF$)$ of the coil? $(3$ mark$)$
