It. The Froude number is a number that defines fluid flow. Using dimensional analysis and showing all your workings show that the Froude number is dimensionless, given that

Froude number (Fr)= velocity of flow(u) /(acceleration due to gravity(g) x hydraulic depth(D)) ^1/2

where u is the velocity of the flow, g is the acceleration due to gravity and D is the hydraulic depth of the water.
