Please help with question 3 of fluids question, it refers to one which is posted first

1. A conveyor belt moving vertically through a viscous liquid bath. The volume flowrate of the liquid raised by the conveyor Q(dependent variable) is a function of the follow ing independent variables; fluid viscos ity , the fluid density p. gravitational acceleration g. the thickness of the liquid layer on the belt h, and the belt velocity V Perform a dimensional analysis for this problem. Use p, v, h as the repeating parameters a) How many non-dimensional parameters will result? Justify your answer. b) Find a non-dimensional parameter that includes Q c) Find a non-dimensional parameter that includes d) Find a non-dimensional parameter that includes V e) Write a proper function between the non-dimensional parameters Q volume flowrate Belt moving upwards with velocity V Fluid surface Liquid layer thickness h Fluid p. Conveyor pulley 3 a) In problem 1, giive a common name for the non-dimensional parameter that includes u (fom part Ie) b) In problem 1, give a common name for the non-dimensional parameter that includes v (from part 1d) c) In problem 2, interpret the parameter I= F, / P«°D¢ to give common name for this non-dimensional parameter. Hint: work on the denominator.
