RE: Engine Cooling - Inlet & Exit
Gentlemen - Man your textbooks!
How does cooling air flow thru the cowling ? Is is blown in - (increasing pressure in the cowl -then looking for avenues of escape)
Or
Does a low pressure outlet decrease pressure in the cowl - allowing the inlet air to readily flow .
PS-Leave out referrences to the air cooled VW's where a fan in a box is used .
