QUESTION 8
On a Mollier diagram show all the stagnation and static points required to represent the
complete flow process in a diffuser
Air enters a diffuser with an average velocity of 375 m/s at a
temperature of 360 kPa and 470 K respectively and leaves at a stagnation pressure of 300 kPa
with an average velocity of 120 m/s and a static pressure of 280 kPa.
stagnation pressure and
Determine
(i) The static pressure and Mach number of the air at inlet
(ii)The diffuser efficiency,
(iii)The Mach number at exit and the overall entropy increase.
