The mass flow rate is given as 11 .973 kg / seconds
The outlet area is given as 1.548 m³
How to solve for the mass flow rate
we have
1000 / 0.287 x (600 + 273)
= 3.991 kg/m3
The mass flow rate = 3.991 x 0.1 x 30
= 11 .973 kg / seconds
Next we have to solve for the outlet area
100 / 0.287 x (200 + 273)
= 0.7633 kg/m³
The outlet area = 11.973 / 0.7366 x 10.5
= 11.973 / 7.7343
= 1.548
In conclusion the calculations are as follows
mass flow rate = 11.973
the outlet area is solve to be 1.548
