The problem of separation of uranium isotopes in a concurrent gas centrifuge is solved analytically. Separative power of the optimized concurrent gas centrifuges equals to δU=12.7(V/700~\rm m/s)2 (300 ~\rm K/T)L, ~\rm kg ~SWU/yr, where L and V are the length and linear velocity of the rotor of the gas centrifuge, T is the temperature. This formula well agrees with an empirical separative power of counter current gas centrifuges. The optimal value of the separative power is not unique on the plane (pw,vz), where pw is pressure at the wall of the rotor and vz is axial velocity of the gas. This value is constant on a line defined by the equation pwvz=constant. Equations defining the mass flux and the electric power necessary to support the rotation of the gas centrifuge are obtained.
