Astrosociology, sociology of outer space, or sociology of the universe [1] is the study of the relationship between outer space, extraterrestrial places, and the wider universe and society. It is an interdisciplinary study between space-related sciences and sociology that seeks to understand the impact of human society outside our current ...
Note that before and after the shock the isentropic relations are valid and connect static and total quantities. That means, p t o t a l ≠ p s t a t i c + p d y n a m i c {\displaystyle p_{total}\neq p_{static}+p_{dynamic}} (comes from Bernoulli, assumes incompressible flow) because the flow is for Mach numbers greater than unity always ...
In fluid dynamics, an isentropic flow is a fluid flow that is both adiabatic and reversible. That is, no heat is added to the flow, and no energy transformations occur due to friction or dissipative effects. For an isentropic flow of a perfect gas, several relations can be derived to define the pressure, density and temperature along a streamline.
The isentropic stagnation state is the state a flowing fluid would attain if it underwent a reversible adiabatic deceleration to zero velocity. There are both actual and the isentropic stagnation states for a typical gas or vapor. Sometimes it is advantageous to make a distinction between the actual and the isentropic stagnation states.
Isentropic analysis of the 300 kelvin isotrope and the weather satellite image of clouds during a blizzard in Colorado In meteorology , isentropic analysis is a technique used to find the vertical and horizontal motion of airmasses during an adiabatic (i.e. non-heat-exchanging) process above the planetary boundary layer .
Point 3 labels the transition from isentropic to Fanno flow. Points 4 and 5 give the pre- and post-shock wave conditions, and point E is the exit from the duct. Figure 4 The H-S diagram is depicted for the conditions of Figure 3. Entropy is constant for isentropic flow, so the conditions at point 1 move down vertically to point 3.
For isentropic compression, ν ( M 2 ) = ν ( M 1 ) − θ {\displaystyle \nu (M_{2})=\nu (M_{1})-\theta \,} where, θ {\displaystyle \theta } is the absolute value of the angle through which the flow turns, M {\displaystyle M} is the flow Mach number and the suffixes "1" and "2" denote the initial and final conditions respectively.
Social entropy is a sociological theory that evaluates social behaviours using a method based on the second law of thermodynamics. [1] The equivalent of entropy in a social system is considered to be wealth or residence location. [2]
