The Prantl-Meyer function can be applied to reflecting shocks and is a function of Mach number and gamma. It does hold for real gases and chemical reactions.
The Prantl-Meyer function, which measures the compression and expansion waves in a compressible flow, is applicable to reflecting shocks. So, the statement that it can be applied to reflecting shocks is TRUE (T).
The Prantl-Meyer function is a function of the Mach number and the ratio of specific heats (gamma). Therefore, the statement that it is a function of Mach number and gamma is TRUE (T).
However, the Prantl-Meyer function does hold for real gases and chemical reactions, as it is a mathematical function used to calculate certain flow properties, specifically for compressible fluids.
