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 ...
This paper reports analytical relations for the thermodynamic properties enthalpy, entropy, heat capacities at constant pressure and temperature of the rep... A.,Stegou-Sagia - 《International Journal of Energy Research》 被引量: 15发表: 1997年 On the three exponents of the isentropic change of ...
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...

(a) Using the isentropic relations of this chapter, what is the critical pressure (the pressure for which the flow is choked)? Assume that the atmospheric temperature is 70 F and the atmospheric density is 2.38×10−3slug/ft3. (b) For part ...
working with resorption-compression [1].In this paper, the thermodynamic changes of an ammonia-water mixture in the vapor phase, along an isentropic expansion, have been calculated numerically for a starting point with a temperature of 800掳C and initial pressures of 20, 30, 40, and 50 bar....
