If positive, fluid will tend to leave the capillary ( filtration ).

If negative, fluid will tend to enter the capillary ( absorption ).

If the brake fluid is old and has absorbed moisture it thus has a lower boiling point and brake fade occurs sooner.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

If a larger fire is necessary, the smith increases the air flowing into the fire as well as feeding and deepening the coke heart.

If they become plugged by debris, water begins flowing over the outside, depositing more calcite and creating the more familiar cone-shaped stalactite.

If a signal is applied to the grid, it modulates the current flowing from the filament to the plate.

If a squirt did occur, it was generally up to the operator to grab the hell bucket and catch the flowing lead.

If the erupted jet is unable to heat the surrounding air sufficiently, convection currents will not be strong enough to carry the plume upwards and it falls, flowing down the flanks of the volcano.

If using a black water tank flush system in a campsite, the use of a back-flow preventer on the end of the hose to prevent sewage from flowing into the potable water system is recommended.

If we assume that equation ( 1 ) represents a flowing medium of constant area, we can sub-divide the spatial domain,, into finite volumes or cells with cell centres indexed as.

If the plasma ( or one ionic component of the plasma ) is flowing in the direction of the line of sight to the observer, emission lines will be seen at a different frequency due to the Doppler effect.

If adaption is thwarted, the psychic energy will stop flowing, and regress.

If we assume that the fluid is constrained to remain on the streamline and if we assume the two ends of a finite length of the tube are at different levels and the fluid is flowing up from an initial velocity and a cross sectional area to a level with velocity and area therefore we can have the Bernoulli ’ s equation given as

If the rising salt diapir breaches the surface, it can become a flowing salt glacier.

If the amount of water flowing into a lake is less than the amount evaporated, the lake will eventually disappear and leave a dry lake ( also called playa or salt flat ).

If current is flowing through the load contacts it will cause arcing across the contacts when they open.

If circuit 2 is an audio system, and circuit 1 has large AC currents flowing in it, the interference may be heard as a 50 or 60 Hz hum in the speakers.

If the contents of mind are like pails and buckets floating in a stream, and the mindstream is like the dynamic flowing of the water, pure awareness is like the water itself in its essential wetness.

If the central bank were to conduct open market operations in the domestic bond market in order to offset these balance-of-payments-induced changes in the money supply — a process called sterilization, it would absorb newly arrived money by decreasing its holdings of domestic bonds ( or the opposite if money were flowing out of the country ).

If a proposed government-backed Pacific port is built at Punta Colonet, Baja California, goods flowing to US states like Arizona and Nevada could bypass the congested Los Angeles region with closer access those markets, providing increased competition with Lázaro Cárdenas.
