Carbon dioxide enters an adiabatic nozzle steadily at 1 MPa, 518 oC, and mass flow rate of 5,322 kg/h and exits the system at 96 kPa and 421 m/s. Considering the nozzle having an inlet area of 37 cm2, calculate the inlet velocity in m/s

The velocity at the nozzle at inlet = 3584

Explanation:

Pressure at inlet = 1 × Pa

Temperature at inlet = 518 ° c = 791 K

Mass flow rate = = 88.7

Gas constant for carbon die oxide is R = 189

Mass flow rate inside the nozzle is given by the formula = × ×

⇒ = = 1 × Pa

⇒ R = 791 × 189 = 149499

⇒ = 0.0037

Put all the above values in above formula we get,

⇒ 88.7 = × 0.0037 ×

⇒ = 3584

This is the velocity at the nozzle at inlet.
