(at the center). Drive the expression for the drag force per unit area applied to both plates by the fluid (F/A). If the drag force is 0.565 N, calculate the necessary velocity for the water at 20°C flow through the tube with the radius of 0.08 m and 15 m length (u:0.0010 kg/m. s).

Question
One dimensional flow occurs in the circular tube at the location adequately far from
the entrance shown in the figure right. Velocity profile is the laminar and expressed as;
U(x) = Umax(1-r/R?)
Where R: radius of the tube, r: distance beginning from the center and Umax: maximum velocity
(at the center). Drive the expression for the drag force per unit area applied to both plates by the
fluid (F/A). If the drag force is 0.565 N, calculate the necessary velocity for the water at 20°C
flow through the tube with the radius of 0.08 m and 15 m length (u:0.0010 kg/m. s).
