At standard temperature and pressure conditions, the bulk modulus [B.sub.o] of air is 1.42 x [10.sup.5] Pa for an isentropic process
. Suppose that I = 20.0 mm, S = 225 [pi][mm.sup.2], [R.sub.o] = 5.0 mm, [R.sub.i] = 4.5 mm, and a = 0.5 mm to 2.5 mm (Figure 1(b)).
This paper gives an in-depth analysis of descriptive functionality of PLAM index, explores contributions of relevant PLAM sensitive parameters in the relatively "static and stable" isentropic processes
, and investigates impacts of the height of pollution mixing layer and vertical atmospheric structure upon the local aerosol density variations.
The Assumption of Local Isentropic Process
. The flow behind the detonation front of aluminized explosive cannot be treated as an isentropic process
approximately due to the chemical reaction of Al particles in the detonation products.
Then it is depressurized through the expansion valve with an isentropic process
. The s-C[O.sub.2] flow leaving the expansion valve will enter the heat exchanger and be cooled by the secondary water flow.
Supposing an isentropic process
in the expander, the leaving velocity [V.sub.2i] can be calculated by
The fluid remaining in the clearance volume undergoes again an isentropic process
until state D is reached, where the pressure differential at the inlet causes the suction valves to open.
where subscript "" refers to the outlet state corresponding to the isentropic process
between the operational inlet and outlet pressures, and [[eta].sub.P] denotes the isentropic efficiency of the pump.
Compressor performance is characterized by its isentropic efficiency which is work from an ideal or isentropic process
divided by actual work Equation (5).
Then, the temperature in the first-stage and second-stage mufflers are estimated by assuming an isentropic process
* Process 4-5: The saturated vapor expands through a turbine to generate power output (ideally an isentropic process
The compressor and turbine were modeled as isentropic processes
discounted by efficiencies of 77% and 71%, respectively.
In classical theory all thermodynamic processes are reversible and adiabatic, known as an isentropic processes
. The small parameter expansion is carried out with a fixed density [[rho].sub.0] of the fluid (SI unit: kg/[m.sup.3]) and pressure [[rho].sub.0] (SI unit: Pa) such that:
