for low pressure effusion of gases

how do I calculate area of pinhole and pinhole diameter?

ln(P/P₀) = -Ct

dP/P = - (A/V)(RT/2πM)^1/2 dt = -C dt

(volume= 285cm³, T= 298.15K)

I got relaxation constant 0.01049 microns/second = C

This is for N2 ( nitrogen)

How do i solve A (pinhole are)?

The gases behave as ideal at low pressure, however, at high pressure they deviate from the ideal behavior. Compare the input power required(in kW)for compressing oxygen gas by first assuming ideal behavior then the real behavior. Take inlet state at 10 MPa, 14°C and the final state after compression is 15 MPa, 127°C. You can ignore the effect of gravity and motion of the system.Assume mass flow rate of the gas as 9 kg/min
