The resistance of flow through co-axial cylinders of which the inner cylinder rotates is studied experimentally, when there are grooves peripherally on the inner cylinder or on the outer cylinder. Results obtained are as follows : 1) When the Reynolds number Re is larger than about 200, the value of resistance coefficient λ of grooved cylinder is much larger than that of no grooves, whether the inner cylinder rotates or not. 2) When rotating Reynolds number Rω is large, the value of λ increases with the increase of clearance. 3) When pitch of grooves is constant, the value of λ increases with the increase of breadth of the grooves.
