Q$3$

The diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor without any work or heat interactions. Calculate the velocity at the exit of a diffuser when air at $100$ kPa and $30C$ enters it with a velocity of $350\frac{m}{s}$ and the exit state is $200$ kPa and $90C.$

$P_1=100$kPa

$T_1=30C$

$v_1=350\frac{(m)}{(s)}$

$P_2=200$kPa

$T_2=90C$
