please provide full calculation

Air is discharged from a large tank through a convergent nozzle
of 25 mm diameter. The air in the tank is at 150 kPa and
temperature of 295 K.
a) determine the mass flow rate when the outside barometric
pressure is 100 kPa.
b) What percentage change in mass flow will result if the
pressure in the tank is 300 kPa for the same barometric
pressure given in (i)?
Take k-1.4, and gas constant, R for air -0.287 kJ/(kg.K)
