Nitrogen, traveling at 12 m/s with a pressure of 14 bar abs. at a temperature of 800 K, enters a device with an area of 0.05 m2 . No work or heat transfer takes place. The temperature at the exit, where the area is 0.15 m2 , has dropped to 590 K. What are (a) the velocity and (b) pressure at the outlet section?

Answer:

(a) 660.70 m/sec

(b) 0.0625 bar

Step-by-step explanation:

In this question, we are asked to calculate velocity and pressure at the outlet section given that both heat and work were not transferred between the two sections.
