For a layer of liquid flowing in a laminar flow in the z direction down a vertical plate or surface, the velocity profile is: v_z = ( ho g delta^2 / 2mu) [1 - (x/delta)^2] Where delta is the thickness of the layer, x is the distance from the free surface of liquid toward the plate, and v_z is the velocity at a distance x from the free surface. Consider the wall to have a depth of w in the y-direction and a length L in the z-direction. (a) Provide a sketch of the system described above with appropriate coordinates and origin point (b) What is the maximum velocity v_z-max? Show that the expression you get has the units of velocity. (c) Derive the expression for the average velocity v_z-av and relate that to v_z-max (d) Derive an expression for the total volumetric flow rate down the wall. Show that the expression you get has the units of m3/s. (e) Calculate the shear acting on the x-surface at x=delta. You are given the relationship between shear and velocities as: au_{xz} = -mu [partial v_z / partial x + partial v_x / partial z]. What are the units of shear you obtain? (f) Calculate the drag force on the wall. What is the unit of drag you obtain?

QUESTION 2: Flow Measurement/Bernoulli Fig 2.1 Water Funnel a. Develop an equation for the velocity exiting the funnel V2 in Figure 2.1 in terms of the dimensions z1 and z2, given the frictional head loss in the tube is 4.25v2^2/(2g). b. Determine V2 and the volumetric rate Q (m^3/s), given the tube diameter is 1.2 cm and the following dimensions: z1 = 53 cm, z2 = -22 cm, z3 = 100 cm, z4 = 40 cm.
