WebExhaust flow rates are based on end-in end-out silencers. Refer to product spec sheets when determining side-in or middle side-in back pressure. Velocity should not exceed 15,000 ft/min regardless of the allowable back pressure (10,000 ft/min for spark arresting silencers). Method 2 If your pressure drop requirement is 1.0" Hg (approximately 13 ... WebAs you lower the back pressure further the flow speed at the throat eventually reaches the speed of sound (Mach 1). Any further lowering of the back pressure can't accelerate the flow through the nozzle any more, because that would entail moving the point where M=1 away from the throat where the area is a minimum, and so the flow gets stuck.
