A clutch apparatus includes a clutch pack including a plurality of friction disks having friction surfaces. The clutch pack may include a plurality of cooling inlets. The clutch pack may selectively transfer torque from a torque supplying member to a torque receiving member. The clutch apparatus may include a rotating manifold having at least a first cooling port for directing a cooling fluid to the clutch pack and at least a portion of the rotating manifold may be coupled for rotation with at least a portion of the friction disks. A fluid-flow area of at least a subset of the plurality of cooling inlets may be dissimilar from other of the plurality of cooling inlets for enabling a desired fluid flow to the friction disks.
