Thank you so much can you hand write clear please 

Air enters an adiabatic nozzle steadily at 300 kPa, 200°C, and 45 m/s and leaves at 100 kPa and
180 m/s. The inlet area of the nozzle is 110 cm:. Determine (a) the mass flow rate through the nozzle,
(b) the exit temperature of the air, and (c) the exit area of the nozzle.
The gas constant of air is 0.287 kPa.m³/kg.K. The specific heat of air is c,= 1.02 kJ/kg.°C.
P = 300 kPa
T = 200°C
V1= 45 m/s
A = 110 cm²
P2= 100 kPa
V2 = 180 m/s
