Check the three statements that are correct.

a) The higher the coefficient of dynamic viscosity, the lower the value of the Reynolds number.

b)The lower the coefficient of dynamic viscosity, the lower the value of the Reynolds number.

c)The physical dimension of the hydraulic diameter is (length squared).

d) In a turbulent regime, space-time changes in the velocity and pressure of a fluid occur.

e)The Reynolds number is used to identify the type of flow, that is, if it is laminar or turbulent.
