Question: Through a packed bed with length L, nitrogen is flowing under isothermal conditions. The pressure just at the beginning of the bed (p1 at x

Through a packed bed with length L, nitrogen is flowing under isothermal conditions. The pressure just at the beginning of the bed (p1 at x = 0) is 3 bar. At the end of the bed the pressure (p2 at x =L) is 1 bar. At what distance from the beginning of the bed is the pressure 2 bar? Assume nitrogen to be an ideal gas.
