In a two-phase mixture of solid particles in an inviscid compressible fluid the effective density of the mixture differs from the average density due to relative accelerations between the phases. The effective density directly influences the effective speed of sound. A constructive theory is given ...
The speed of sound in a fluid is determined by, and therefore an indicator of, the thermodynamic properties of that fluid.In this sentence, the writer presentsA.ImplicationB.MethodologyC.Background factual informationD.Methodology的答案是什么.用刷刷题APP
Mach is defined as "the ratio of the velocity of a rocket or a jet to the velocity of sound in the medium being considered." When a plane passes the sound barrier-flying faster than sound travels' listeners in the area hear thunderclaps, but the pilot of the plane does not hear them....
The distance travelled per unit time by a sound wave travelling in an elastic medium is known as the speed of sound. The speed of sound in a given medium depends on the elasticity and density of that medium. The higher the sound speed, the greater is the elasticity and the lower is the...
An apparatus and a method for measuring a speed of sound in a fluid in a well bore may include a frame adapted to receive the fluid there through are provided. The apparatus includes an acoustic source mounted on the frame; an acoustic detector to measure a signal propagating through the ...
This application computes and tabulates the speed of sound in various fluids at standard temperature and pressure, as provided by the ThermophysicalData package (which uses the open-source CoolProp project for fluid properties). The list of fluids include water, ethanol, air, ammonia and several...
Development of a fundamental equation of state for the liquid region of a pure fluid from speed of sound measurements. Application to water The prediction capability of the method is presented for water as the interest fluid, over an extended pressure and temperature range of the liquid region.....
