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
