Carbon dioxide enters an adiabatic nozzle steadily at 1 MPa, 530 oC, and mass flow rate of 5,227 kg/h and exits the system at 102 kPa and 427 m/s. Considering the nozzle having an inlet area of 43 cm2, calculate the inlet velocity in m/s (Give your answer with three decimals, and do NOT enter units!!!).
