Any help is appreciated!

In a chemical coating process a belt is moving with a constant speed of V=2 m/s. Belt is drawing up a liquid film with a thickness h=2 mm. The flow of the liquid is assumed to be steady, laminar and fully-developed. The belt is b=l m wide in the L direction. The liquid film is open to the atmosphere and the friction between the liquid and the air could be neglected. a(25). Using Navier-Stokes equations show that the pressure field within the liquid is constant i.e. P=Patm and the velocity profile is u=[g/(2v)y2-(gh/v)y+V. Do it step by step showing every assumption and simplification. b(10). If shear stress on the belt surface Tw is a function of p,h,g, find the dimensionless groups that represent this problem using Buckingham-n theorem, i.e find . Using results in part a and b, find the function f in part b. What is the power used by the belt to draw up the liquid? What is the volume flow rate of the liquid Q(m3/s)?

Explanation / Answer

i can help a little bit..but i cant solve the whole problem..it seems to be very complicated..but i have a little bit idea for this kind of problem
