Flashcards in Chapter 7 Thermo Review Deck (20):
1

inviscid flow

flow with friction

2

incompressible flow

density remains constant

3

Bernoulli's Equation holds only for (2)

1. incompressible flow
2. inviscid flow

4

Euler's Equation is used instead of Bernoulli's Equation when flow is

compressible

5

Bernoulli's Equation and Euler's Equation are both expressions of

F=ma

6

purpose of Bernoulli Equation

relate properties of different points along streamline

7

reversible flow

no dissipative phenomena occurs, where viscosity, thermal conductivity, and mass diffusion are absent

8

isentropic flow

without gain or loss of entropy, adiabatic, frictionless flow, no change in entropy, adiabatic and reversible, no energy transformations due to friction, reversible

9

adiabatic

heat does not enter or leave system

10

homogenous

density and composition are same throughout

11

specific heat

measure of heat capacity of system

12

enthalpy

measure of heat content of a system

13

entropy

measure of the amount of energy of a system that is unavailable for the product of work

14

stagnation condition

flow is stopped adiabatically, isentropic energy converted to heat/pressure, allows calculation of TOTAL pressure and TOTAL temperature

15

stagnation temperature

TOTAL temperature of the flow if stopped isentropically

16

incompressible flow

density is constant, temperature is constant

17

compressible flow

adiabatic and frictionless

18

2 types of pressure

1. static
2. total (stagnation)

19

total pressure measured via

pitot tube

20

total pressure measured via

pitot-static tube
