Question

Reynald no. (Nr )is at constant and depend on the
value of velocity (v), density (p) and coefficient of viscosity n. Also Nr is directly proportional to the diameter (D) of the pipe. this constant enable us
to find the weather flow is streamline or not . using method of dimensions, derive the formula for Nr.
