I need the answer quickly
Example (4-6): At a point in a flow passage, the velocity and
temperature of the air are 710 m/s and 450 K respectively.
Calculate:
(a) The stagnation speed of sound.
(b) The critical speed of sound.
(c) The Mach Number and the Mach Number referred to
critical condition at a given state.
(d) If the air is accelerated in a suitable flow passage, find the
maximum possible velocity that can be attained and the
Mach Number referred to critical condition corresponding
to the state of maximum velocity.
