A viscоus liquid fоrms а cоnstаnt-thickness film of thickness hhh flowing in lаminar motion down a plate inclined at an angle θthetaθ, as shown in the figure. The velocity profile is given by u(y)=Cy(2h−y),v=0,w=0u(y)=Cy(2h-y), qquad v=0, qquad w=0u(y)=Cy(2h−y),v=0,w=0 where CCC is a constant. Task Using the momentum equation for steady laminar flow down an incline, determine the constant CCC in terms of the fluid properties and the plate angle θthetaθ. Select the correct answer: A. C=gsinθ2displaystyle C=frac{gsintheta}{2} B. C=ρsinθμdisplaystyle C=frac{rho sintheta}{mu} C. C=ρgsinθ2μdisplaystyle C=frac{rho gsintheta}{2mu} D. C=2ρgsinθμ2displaystyle C=frac{2rho gsintheta}{mu^2}
