You are an engineer getting ready to go meet the mayor on the new building development project going on downtown. The mayor has concerns that the building has been built a lot taller than what it was supposed to be. As you stand on top of the building with the mayor, you realize that you forgot your tape measure (but you do have your cell phone). Using just your cell phone and your knowledge of kinematics equations (and maybe a nearby rock), you must impress the mayor with how smart you are and reassure him the building is the proper height. Explain how you could use your cell phone and a specific kinematic equation to estimate the height of the building.

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.
