Chapter 11.1, Problem 1P

To determine

The difference between the ideal gas flow and the inviscid flow.

Explanation of Solution

Ideal gas is a hypothetical concept whose properties are defined using ideal gas equation.

Write the expression of the ideal gas equation.

    $PV=nRT$                                                                          (I)

Here, the absolute pressure of an ideal gas is $P$, the temperature of an ideal gas is $T$, the volume of an ideal gas is $V$,the ideal gas constant is $R$, the number of moles of the gas is $n$.

For the flow of an ideal gas, it may or may not have viscosity in flow.

The flow of fluid which counters zero viscosity in flow is called inviscid flow. For the inviscid flow fluid may or may not be ideal.
