= coordinates, as shown. Two immiscible fluids flow in the x direction driven by a pressure gradient. The fluids are located between fixed parallel plates that are infinitely long in the third (z) direction. Fluid 1 is between y : 0 and y = hq, while fluid 2 is between y hy and y = h2. The gradient of dynamic pressure driving the flow is a constant, and is the same in each fluid, but the viscosity of each fluid is unique. 55 points. y = hz- P. 42 Flow y = h --- Direction P.M1 x y = 0 - (a) Identify the component of Navier-Stokes needed to solve for velocity; write all of its terms. (d) Which (other) conservation law can be used to verify the assumption of fully-developed flow? Both name and write the equation
