A commonly used equation for calculating the velocity of uniform flow in open channels (v) is

where vis the velocity of uniform flow, n is the Manning coefficient, R is the hydraulic radius, and


 is the bed slope. Find the dimensions of the Manning coefficient to ensure that the equation is homogeneous.
