Answer
We know that
mass flow rate = Density $\times$(volume flow rate)
As Mass flow rate is given we just need to find density.
For finding density ,
we will use the ideal gas equation, we could have checked the data for specific volume in the table , but it is air , for which their is no such table.
By ideal gas equation we can write,
D=PM/RT
(M is molar mass )
The average molar mass of dry air is 28.97 or 29 approx.
by using the value ,
we get density
as 1.652.
By using the value of density in th above eqn , we get volume flow rate as 6.96 kg/sec.
