Velocity profiles are measured at the upstream end and at the downstream end of a control volume as shown in Figure. The maximum velocity at the inlet and at the outlet is the same V=Vmax. =3m/s. The velocity profile at the inlet is uniform, while the velocity profile at the outlet is linear as shown in figure. If the fluid is air, with p=1.22 Kg/m³ and H=lm, calculate the drag per unit length on the wall.

Figure. The maximum velocity at the
inlet and at the outlet is the same
V=Vmax. =3m/s. The velocity profile at
the inlet is uniform, while the velocity
profile at the outlet is linear as shown in figure. If the fluid is air, with p=1.22 Kg/m³ and H=1m,
calculate the drag per unit length on the wall.
