4. Solution to the given CAC problem:

1)	CAC Inlet mass flow rate and temperature value selection		2)	CAC inlet and outlet diameter value selection
3)	CAC Pressure drop settings		4)	CAC length value selection
5)	CAC outlet pressure and temperature value selection		6)	Case setup
7)	Plot Setup		8)	Data Storage setting from Output setup
9)	GT Post while Simulation Running		10)	CAC average heat transfer rate
11)	Pressure deop across CAC		12)
				1) CAC Average Heat transfer rate is around - 8.68 kW. 2) Pressure drop across CAC comprises of Pressure drop at cooler inlet - 0.00111 bar, Pressure drop across cooler - 0.0837 bar, Pressure drop at cooler outlet - 0.00224 bar. Thus overall pressure drop across CAC is 0.087 bar.
