Question six

(a) Write short notes about the following as they are applied in fluid mechanics

(i) Uniform flow.

= Uniflow is a flow in which the velocity is the same at a given instant at every point in the fluid.

(ii) Uniform stead flow

This flow is the one in which all conditions at6 any point in a stream remains constant with respect to time, here the quantity of liquid flowing per second through any section is constant.

(b)Consider a cylinder of fluid of length L and radius R flowing steadily in the center of a pipe of radius r as shown below.

Show that when the flow in the pipe is laminar the pressure loss is directly proportional to the velocity and obeys the equation.

Where v is the velocity D is the diameter of the pipe
