Transcribed Image Text:Question 3. Water flows steadily past a porous flat plate. Constant suction is applied along the porous section ad to generate a constant velocity vo = -0.2 mm/s. The velocity profile at section cd is: # = 3 []– 2115 и %D The velocity profile at section ab is constant U = 3m/s. Estimate the mass flow rate (in kg/s) across section bc. U = 3 m/s 8 = 1.5 mm Vo Width, w = 1.5 m L = 2 m

Expert Solution

Step 1

Solution:

given that

v0 = -0.2 mm/s

velocity profile at section cd is

$\frac{u}{U} = 3 [\frac{y}{δ}] - 2 {[\frac{y}{δ}]}^{1.5}$
