i wan the answer of question

Air is steadily accelerated in a nozzle. It enters the nozzle with a velocity of 30 m/s and an area of 80 cm? The air exits the nozzle with a velocity of 180 m/s as shown in the figure below. The density of air is given to be 2.21 kg/m3 at the inlet, and 0.762 kg/m3 at the exit. Determine the mass flow rate at the exit in kg.s and the exit area of the nozzle. V1= 30 m/s Al=80 cm? V1= 180 m/s Select one: O a. mass flow rate =0.35 kg/s and A=25.7 m? O b. mass flow rate =0.33 kg/s and A=7.38 m² O c. mass flow rate =0.53 kg/s and A=38.7 m?
