The poloidal and parallel plasma viscosities in tokamak geometry in Hamada coordinates are calculated from the drift kinetic equation, including a large mass flow velocity without imposing the usual constraint that {ital V}{sub {ital p}}{ital B}/({ital v}{sub {ital ti}}{ital B}{sub {ital p}}) be small. Here, {ital V}{sub {ital p}} is the poloidal plasma flow velocity, {ital v}{sub {ital ti}} is the ion thermal speed, {ital B} is the magnetic field strength, and {ital B}{sub {ital p}} is the poloidal magnetic field strength. With this extended validity, the poloidal and parallel viscosities are useful in modeling the radial electric field in the edge region of a tokamak in the enhanced confinement regime.
