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!!!).

The inlet velocity is 5.015

Explanation:

Given that,

Mass flow rate m, = 5227kg/h

Pressure P₁ = 102kPa

Inlet area A₁ = 43cm² = 0.043m²

Exit velocity v₂ = 427m/s

For CO₂ gas

R = 0.1889KJ/Kg.k

R  is specific gas constant

Calculate the density

Calculate the inlet velocity

The inlet velocity is 5.015

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)
