7.2.5.3.3 Adiabatic gas horsepower The adiabatic gas horsepower is determined from the following equations: (7.31)GHP=wHad33,000ηad where: GHP = gas horsepower The break horsepower (BHP), which accounts for mechanical efficiency, can be determined from the following equation: (7.32)BHP=0.085...
In this paper, we consider limit behaviors of Riemann solutions to the isentropic Euler equations for a non-ideal gas (i.e. van der Waals gas) as the pressure vanishes. Firstly, the Riemann problem of the isentropic Euler equations for van der Waals gas is solved. Then it is proved that...

In previous publications, three isentropic exponents, k pv, k Tv, k pT, have been introduced, which when used in place of the classical isentropic exponent k = c p c v in the ideal gas isentropic change equations, the latter can describe very accurately the isentropic change of real gases...
In previous publications, three real gas isentropic exponentsk pv ,k Tv ,k pT have been introduced, which when used instead of the classical isentropic exponentk=c p /c v in the ideal gas isentropic change equations, the latter may be applied with great accuracy to real gases. The first ...

Differently from single equation methods rooted in the ideal gasdynamics, the new approach is based on the system of two nonlinear equations imposing the equality of total pressure and velocity, assuming as unknowns the two values of densities, on both sides of the contact discontinuity. Newton ...
If the fluid can be assumed to be an ideal gas, we can also make use of the ideal gas laws, described in Eqs. (9.16) through (9.18). If there is heat being transferred during the flow conditions but there is no friction, then the equations to describe the flow field will take the...
