If, for some reason such as economy, we are not going to develop aircraft nuclear propulsion with a sense of national urgency, then we should turn our effort to developing jet engines with a thrust-to-weight ratio of 12 or 15 to one.

If a person ‘ synthesizes ’ a ‘ jet plane landing ’ sound, this is achieved mostly by altering the shape of the mouth to filter the white noise into pink noise by removing the higher frequencies.

If a jet aircraft is at full throttle but is tied to a very strong tree with a very strong chain, then the jet engine produces no propulsive power.

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 the jet emits a burst of energy every minute in its own rest frame this may be observed on Earth as being a much faster release, perhaps one burst every ten seconds.

If ( i. e. when velocity of jet is close to the velocity of light ) then despite the fact that < math >

He reported a narrow escape when, at the foot of the mountain, a jet of steam came out of the ground over which he and his party had just passed: " If it had struck any one of us we would have been scalded to death ".

If the nozzle pressure ratio is above the critical value ( about 1. 8: 1 ) a convergent nozzle will choke, resulting in some of the expansion to atmospheric pressure taking place downstream of the throat ( i. e. smallest flow area ), in the jet wake.

If an incoming HEAT jet penetrates the outer shell and forms a bridge between the shells, the electrical energy discharges through the jet, disrupting it.

If the associated jet stream is stronger than normal and there is colder than normal air in place in central Canada to provide a greater than normal temperature contrast with Gulf of Mexico moisture drawn northward by the developing panhandle low, surface cyclogenesis can be particularly energetic and cause a great swath of heavy snow to develop and blanket a large portion of the American Great Plains and upper-midwestern states in conjunction with very strong winds, the combination of which exceeds blizzard criteria.

If the molecular cohesion of the liquid is sufficiently high, stream breakup does not occur ( if it does, droplets are electrosprayed ) and a charged liquid jet is formed.

If the jet is oriented along the line of sight to Earth, relativistic beaming will change its apparent brightness.

If M and N are two smooth manifolds, how do we define the jet of a function?

If the mouth is open the jet may project several feet.

If the jet turns into very fine fibers instead of breaking into small droplets, the process is known as electrospinning.

If the jet wave is survived, there is a short respite, then the next round of helicopters begins with an extra row of helicopters on the first run.

If the jet had an opening angle of only a few degrees, the burst energy could have been thousands of times lower.

If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot.

If engine installation takes 20 minutes, hood installation takes five minutes, and wheel installation takes 10 minutes, then a car can be produced every 35 minutes.

If the engine is running with clutch engaged and the transmission in neutral, the engine spins the input shaft of the transmission, but no power is transmitted to the wheels.

If the nominal compression ratio of an engine is given, the pre-ignition cylinder pressure can be estimated using the following relationship:

If a compression test does give a low figure, and it has been determined it is not due to intake valve closure / camshaft characteristics, then one can differentiate between the cause being valve / seat seal issues and ring seal by squirting engine oil into the spark plug orifice, in a quantity sufficient to disperse across the piston crown and the circumference of the top ring land, and thereby effect the mentioned seal.

If the engine is sent on 99104, it should arrive on 99139.

If one knows the actual URL of a website that features sexual explicit or 18 + content, they have the ability to access it without using a search engine.

If the initial value of a polynomial ( and of its finite differences ) is calculated by some means for some value of X, the difference engine can calculate any number of nearby values, using the method generally known as the method of finite differences.

If a petrol engine were to have the same compression ratio, then knocking ( self-ignition ) would occur and this would severely reduce the efficiency, whereas in a Diesel engine, the self ignition is the desired behavior.

If somebody tries to associate a second engine with a given car, we want the DBMS to deny such a request and display an error message.

If at least 50 cars had been built, sportscars like the GT40 and the Lola T70 were allowed, with a maximum of 5. 0 L. John Wyer's revised 4. 7 litre ( Bored to 4. 9 litres, and o-rings cut and installed between the deck and head to prevent head gasket failure, a common problem found with the 4. 7 engine.

If the system is shut down suddenly ( pulling into a service area after a high speed drive and stopping the engine ) the oil that is in the turbo charger immediately oxidizes and will clog the oil ways with deposits.

If this is around 1 the engine is said to be " square ", if it is greater than 1, i. e. the bore is larger than the stroke, it is " oversquare ".

If " carb-icing " is an issue, plenty of waste engine heat is available to prevent trouble.

* If the boat has an internal combustion engine anyway, then its alternator will provide significant charge when it is running.

If a server is being indexed by Google or another search engine during peak periods of activity, or does not have a lot of available bandwidth while being indexed, it can also experience the effects of a DoS attack.

If the electronic motor required to move the pistons which raise or lower the engine is malfunctioning, every outboard motor is equipped with a manual piston release which will allow the operator to drop the motor down to its lowest setting.

If the driver is far away, he will increase his engine speed to close the gap.

If attention is to be obtained, the engine must be such that the engineer will be disposed to attend to it.

If the engine must be operated in any orientation ( for example a chain saw ), a float chamber cannot work.

If you wanted this much power in a Pontiac, it was only available in the top-of-the-line 421 HO Tri-Power engine that was not standard in any Pontiac model, but an extra-cost option.

If comparable bore to stroke ratios are employed, an engine with more cylinders will have a greater piston area and a shorter stroke.

If the engine misfired or the burn was not completed, the probes would be left in Earth orbit and given a Kosmos designation.

If his circumspection in regard to Philip's sensibilities went so far that he even refused to grant a dispensation for the marriage of Amadee's daughter, Agnes, to the son of the dauphin of Vienne -- a truly peacemaking move according to thirteenth-century ideas, for Savoy and Dauphine were as usual fighting on opposite sides -- for fear that he might seem to be favoring the anti-French coalition, he would certainly never take the far more drastic step of ordering the return of Gascony to Edward, even though, as he admitted to the English ambassadors, he had been advised that the original cession was invalid.
