$($Show work and steps. Circle$/$box final answers$)$ Problem $1$

Air enters a constant area duct at a pressure of $620$ kPa and a temperature of $300^($@$)$C$,$ the velocity

at the inlet being $100$m$//$s$.$ If the velocity at the exit to the duct is $210$m$//$s$,$ determine:

$($a$)$ The pressure, temperature, stagnation pressure, and stagnation temperature at the exit to the

duct.

$($b$)$ Also, find the heat transfer per unit mass in the duct. Assume that the effects of viscosity are

negligible
