Air enters a duct, of diameter D=25.0 mm through a well-rounded inlet with uniform speed, U₁=0.870 m/s. At a downstream section where L=2.25 m, the fully developed velocity profile is u(r) 2 (² Uc R The pressure drop between these sections is p₁-P2 = 1.92 N/m². Find the total force of friction exerted by the tube on the air. U₁ = 0.870 m/s L= 2.25 m- D = 25.0 mm (2)

Question
Air enters a duct, of diameter D=25.0 mm through a well-rounded inlet with uniform speed, U₁=0.870 m/s. At a downstream section where L=2.25 m, the fully developed velocity profile is u(r) (7) ² Uc The pressure drop between these sections is p₁ - P2 = 1.92 N/m². Find the total force of friction exerted by the tube on the air. U₁ = 0.870 m/s x -L= 2.25 m D = 25.0 mm 2
