Step: 1

Given data
The density at the inlet of the nozzle 
The velocity at the inlet is 
The inlet area 
The density at the outlet of the nozzle 
The velocity at the outlet is 

 

Step: 2

(a)
The mass flow rate



 

Step: 3

(b) The exit area of the nozzle
Since the process is steady mass flow rate remains constant in the nozzle, the exit area can be determined as
