Question

Question 2 free surface fluid 1 fluid 2 fR h2 plate moves at constant speed U Figure 2: Bottom plate moves at constant speed under two unmixed fluids Consider a two-dimensional Newtonian, steady state, incompressible flow of two fluids over an infinite horizontal plate moving at speed U 1 m/s, as shown in figure 2. Fluid 1 t; water with a denai y Pi IIXX? kr/m", a dyiuunic ven rity of ,4 1 x 10-s 1.ati, iuul a depth of h 1 c, while fluid 2 is glycerol with a density p2 1250 kg/m3, a dynamic viscosity of ?2-1 Pa-s, and a depth h2-1 cm. a) Calculate the velocity profile of the flow. State your assumptions and show your work. b) Calculate the mass flow rate per unit width.

I asked this previously and wasn't given an answer, just methods that I could use. It was really unhelpful. I woudl thankful to whoever actually solves this.

Answer 1

second part of solution

pl comment if any doubt we will there to solve.
