Consider the incompressible, axisymmetric, and steady flow around body. The wake downstream of the body has a velocity profile of: U(r) = Uinf (1- 0.2 (1-r/3)6 - 0.18 (cos( (Tr)/(2×3)) ) ) m/s where r is the distance from the centerline of the streamtube and goes from 0 to 3 m. What is the cross-sectional area of the streamtube far upstream of the body where the flow is at a uniform speed of Uinf? Also, what is the drag coefficient on the body with a reference area of 16 m²? Note: the pressure is constant all the way around the streamtube. Give answers to three decimal places. Cross-sectional area = m2 CD =

Question
Transcribed Image Text:Consider the incompressible, axisymmetric, and steady flow around body. The wake downstream of the body has a velocity profile of:.
U(r) = Uinf (1- 0.2 (1-r/3)6 - 0.18 (cos( (Tr)/(2×3) ) )) m/s
where r is the distance from the centerline of the streamtube and goes from 0 to 3 m. What is the cross-sectional area of the streamtube far
upstream of the body where the flow is at a uniform speed of Uinf? Also, what is the drag coefficient on the body with a reference area of
16 m2? Note: the pressure is constant all the way around the streamtube. Give answers to three decimal places.
