1. The viscous PDMS (Polydimethylsiloxane) coated on the glass (Sylagard 184, Dowcoaning) is using the spin coating material. If we fix the viscosity, density of coating material, initial thickness at 4000 cP, 965 kg/m3 and 0.105 cm, and then, the rotation time is fixed at time of 300s and the rotation of device start from 500 to 6000 RPM. Calculate the final thickness of the film at angular speed from 500-6000rpm (step by 500rpm) and draw the relationship between the final thickness (h) and angular speed (w).

Derive an expression for the shear stress acting on the top plate Tw. Q' is the flow rate per unit width (i.e. has units of m^2/s). Express Q' in terms of Tw. When the flow rate per unit width is Q'=1.2*(10^-4) m^2/s, the gap between the plates is 5mm, he device estimates the shear stress at the top wall to be -0.05 Pa. Estimate the viscosity of the fluid. When the tests are repeated for blood ample, different estimates of viscosity are found for different flowrates. What does this tell you about the viscosity of the flow? Use appropriate terminology. As the pressure gradient is increased, at a certain point the measurements cease to be reliable. Using knowledge of fluid mechanics, give a possible reasonfor this. Use appropriate terminology.
