Air enters a diffuser witha velocity of 400 m/s, a pressure of 1 bar and temperature of 25 c. it exits with a temperature of 100 c. what is the exit velocity of the air? assume there are no heat losses or change in potential energy data: = 0.718 kj/kg.°c. mw = 28.9 g/mol

Exit velocity of air is 96.43 m/s.

Explanation:

Given that

For air

Now from first law of thermodynamics for open system at steady state

For diffuser

We know that

So the exit velocity of air is 96.43 m/s.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
