To maximize the mass flow rate of air through a given nozzle, which properties To maximize the mass flow rate of air through a given nozzle, which properties should I try to change and in which direction, higher or lower?

should I try to change and in which direction, higher or lower? The mass flow rate is given by Eq.16.41 and if we have

The mass flow rate is given by Eq.16.41 and if we have M M = 1 at the throat= 1 at the throat then Eq.16.42 gives

then Eq.16.42 gives the maximum mass flow rate possible.the maximum mass flow rate possible. Max flow for:

Max flow for:

Higher upstream stagnation pressure Higher upstream stagnation pressure Lower upstream stagnation temperature Lower upstream stagnation temperature
