Backpressure

Often such well head units do not have a condenser, and are called backpressure units. ❋ Unknown (2009)

The aortic valve, which controls blood blasting out of the heart into the body's main artery, gets narrowed and causes backpressure. ❋ M.D. Clive Meanwell (2011)

If the turning vane is not used, some of the air will get around the turn, but backpressure will be created, and the flow rate of the air will be reduced. ❋ Unknown (2007)

Most of the added power is due to a new exhaust system that includes perforated-foils technology in the catalytic converters to meet the stringent levels of the recently approved Euro 5 emission standards while reducing backpressure, retaining less heat and improving flow. ❋ Unknown (2009)

The numbers of cooling fins multiply as they extend from the center of the Ruby Orb to reduce backpressure on the fan and faster heat dissipation. ❋ Unknown (2006)

It fits the trend toward wild graphics/paint/Japanese characters, super annoying backpressure-robbing exhaust coffee cans, huge bookshelf wings, etc. ❋ Kevynwight (2002)

As discussed earlier in connection with alternative operational systems, the problem of backpressure on linings in some circumstances can be an argument against rotational operation of secondary canals. ❋ Unknown (1995)

- Never try to make the water rise above the highest point of resurgence as this could produce a backpressure which would make the flow emerge elsewhere. ❋ Unknown (1994)
