Air Inlets Calculations?

Hi guys,

Is there anyone who could shed some light on how do we calculate the drag caused by the ram air inlet under an a/c belly.Do we use the Drag Polar equation to calculate the amount of drag?

To what extent can the pack 1 & 2 air inlet and air conditioning bay cool air inlet affect the aircraft performance?Is the drag caused by these inlets significant enough to cause a dip in performance or is it negligible?I've attached the link which shows the location of these inlets.
