Air at 403 K and 1 atm enters a convergent nozzle at a velocity of 150 m/s and expands isentropically to an exit pressure of 76 kPa. If the inlet area of nozzle is 5x10-3 m2
, find (a) stagnation temperature, pressure and enthalpy, (b) inlet Mach
number (c) exit temperature, pressure, Mach number and area, (d) what must be the
back pressure, temperature, and flow rate if sonic conditions are attained at exit.
Assume air to be perfect gas.

how is this a question? in order for me to answer it i have to understand the question

explanation:

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
