specific impulse (redirected fromExhaust velocity) Encyclopedia specific impulse n. A performance measure for rocket propellants that is equal to units of thrust per unit weight of propellant consumed per unit time. Also calledspecific thrust.
aThis section shows a clear reduction in velocity at the position of duct A — indicating voiding. Duct B cannot be identified, thus no voiding exists in duct B at this location. 这个部分显示对速度的清楚的减少在输送管A -表明的位置无效。 输送管B不可能被辨认,因而无效不存在于输送管B在这个地...
The CFD study results are used to inform the design of the duct to be used for coil testing in RP-1785 and the final duct design is presented.JuseokChristian K. BachCraig R. Bradshaw
Any sensor/instrument immersed into a duct has a similar effect; the larger the sensor is, the greater the problem. For other types of instruments an analysis must be made, so as not to block a large proportion of the duct cross-section with the meter. A good rule of thumb to avoid ...

The basic idea of the de Prony equation was the basis of systematic calculations by Henry Philibert Gaspard Darcy (1803–1858), a French engineer who designed the water distribution system for the city of Dijon. Darcy also improved the design of the Pitot tube into the form used today. In ...
