* Specific impulse, represented by I < sub > sp </ sub >, a term used to describe rocket and jet engine thrust

* Specific impulse: 1, 100 – 1, 600 s

Specific impulse ( usually abbreviated I < sub > sp </ sub >) is a way to describe the efficiency of rocket and jet engines.

Specific impulse and effective exhaust velocity are proportional.

Specific impulse is a useful value to compare engines, much like miles per gallon or litres per 100 kilometres is used for cars.

Specific fuel consumption is inversely proportional to specific impulse and effective exhaust velocity.

* Specific impulse

This increased fuel consumption offsets somewhat the savings in oxidizer mass ; these losses are in turn offset by the higher Isp ( Specific impulse ) of the air-breathing engine.

As noted the specific impulse of monopropellants is lower than bipropellants and can be found with the Air Force Chemical Equilibrium Specific Impulse Code tool.

* Specific impulse

* Specific impulse

Specific impulse ( Isp ) measures how much thrust can be derived from a given mass of fuel, and is a standard figure of merit for rocketry.

Specific impulse: 224 s

Specific impulse values from 200 seconds to several thousand seconds are possible by choosing the propellant and laser pulse characteristics.

* Specific impulse: 305 s.

* Specific impulse

Specific impulse —

* Specific energy change of rockets

Specific reasons for language change from German to the national language usually derive from the desire of many Germans to belong to their new communities after the end of World War II.

* Specific storage or storativity: a measure of the amount of water a confined aquifer will give up for a certain change in head ;

* Specific relative angular momentum

Specific relative angular momentum plays a pivotal role in the analysis of the two-body problem.

Specific relative angular momentum, represented by the symbol, is defined as the cross product of the relative position vector and the relative velocity vector.

* Specific angular momentum

Specific detectivity, or D *, for a photodetector is a figure of merit used to characterize performance, equal to the reciprocal of noise-equivalent power ( NEP ), normalized per unit area.

Specific fuel consumption of air-breathing jet engines at their maximum efficiency vary more or less inversely with speed, which in turn means that the fuel consumption per mile or km can be a more appropriate comparison metric for aircraft that travel at very different speeds.

Specific volume is volume per mass, the reciprocal of density which equals mass per volume.

Specific radioactivity S is defined as radioactivity per unit mass of the radionuclide:

Specific humidity is the proportion of the mass of water vapor per unit mass of the moist air sample ( dry air plus the water vapor ); it is closely related to humidity ratio and always lower in value.

Specific practices include the use of rapid drumming 220 beats per minute to attain the Shamanic State of Consciousness, communication with " power animals ", and ritual dance.

Specific capacity is a quantity that which a water well can produce per unit of drawdown.

** Specific output: 75. 09 bhp per litre

* Specific heat capacity, in physics, a substance's heat capacity per unit mass, usually denoted by the symbol c or s

Specific energy is defined as the energy per unit mass.

* Specific Output: per litre

* Power-to-weight ratio / Specific energy-energy per unit mass

Specific gravity is the ratio of the density ( mass of a unit volume ) of a substance to the density ( mass of the same unit volume ) of a reference substance.

Specific storage ( S < sub > s </ sub >) and its depth-integrated equivalent, storativity ( S = S < sub > s </ sub > b ), are indirect aquifer properties ( they cannot be measured directly ); they indicate the amount of groundwater released from storage due to a unit depressurization of a confined aquifer.

* Specific volume is the volume of the mixture ( dry air plus the water vapor ) containing one unit of mass of “ dry air ”.

Specific duties varied widely from unit to unit from one year to another.

The second stage, which typical time are one week, it's the Specific Training, in this phase the applicant for Reservist develop the specific tasks in his military unit.
