The invention discloses an isentropic process pressure temperature field device driven by gas and an application of the device. A rigid pressure-proof container (1) with a supporting device is arranged, a set of holes are formed in the container wall, a joint is arranged in the opening of ...
If we can find a relationship that combines enthalpy with the pressure and temperature of a gas, we have found the necessary tools to describe the gas compression process. For an ideal gas, with constant heat capacity, the relationship between enthalpy, pressures, and temperatures is given as:...
In an ideal gas for an isentropic process, the following relationships exist between static properties at any two points in the flow: P2/ P1= ( T2/ T1)[ k / ( k-1) ]= ( ρ2/ ρ1)k where P = static pressure ρ = static density T = static temperature P and T are in absolute...
awhere W is the mass flow, T is the temperature and P is the pressure. The subscripts 1 and 2 refer to the turbine inlet and outlet, respectively. What remains possibly to consider are steam turbine losses and variations with load of the isentropic efficiency. 那里W是流量, T是温度,并且P...

The behavior of various media in conditions of high pressure and relatively low temperature may be studied in the process of isentropic compression. This paper proposes a method of loading the condensed medium by detonation waves with variable energy liberation in the front, and the method is used...
The solubilities of hydrogen cyanide and sulfur dioxide in pure water were measured using a static method in the temperature range 313 ⩽S T/K ⩽ 413 ... B Rumpf,G Maurer - 《Fluid Phase Equilibria》 被引量: 191发表: 1992年 Extension of SAFT-gamma to model the phase behavior of CO2...
Some thermodynamic properties such as energy per particle, pressure, temperature, chemical potential, velocity of sound, adiabatic index and compressibility for normal liquid ~3He have been calculated. Our results indicate that the sound velocity is always less than the velocity of light in vacuum (...
a synoptic chart presenting the distribution of meteorological elements in the atmosphere on a surface of constant potential temperature (equivalent to an isentropic surface); it usually contains the plotted data and analysis of such elements as pressure (or height), wind, temperature, and moisture ...
