2. Consider a flow of liquid in a horizontal circular tube which is mobile. The flow in the tube is assumed to be fully developed and pressures at two ends are Po and PL. The cylindrical tube has radius of R and length of L. The tube itself is moving along the z-direction with a velocity of Vz (R) = -α Trz (R), where a > 0. a) Obtain the radial velocity profile in the circular tube. b) Find the average velocity Hint (Answer): R Z Fluid flows in z- direction L Uz = ΔΡ 4μL ΔΡ 2L - R21 2μ ΔΡ Uavg=8μL R²+ ΔΡ 2L aR - R2V 2μ
