May is tornado season in Oklahoma. According to the National Weather Service, the Poisson rate of tornados in Oklahoma in May is 0.7 per day, based on data from 1950 to the present. The meteorologist is interested in X= the time (in days) from the start of May until the 3rd tornado to occur. Which distribution is an appropriate model for the distribution of X?

You have been asked to design a device to provide steady shearing motion to a liquid of viscosity $\mu$ placed in between two flat plates. The coordinate normal to the bottom plate is y; the distance along the bottom plate is x. The bottom plate is y; the distance along the bottom plate is x. The bottom plate is at y=0 and the top plate is at y=h. The top plate is shearing at a rate U(ulxh) with respect to the bottom plate. Furthermore, a difference in pressure $P_1 - P_2$ with ($P_1 > P_2$) acts from x=0 to x=L, producing a pressure gradient: $\frac{\delta P}{\delta x} = \frac{P_1 - P_2}{L}$ a) Write the differential equation controlling the motion and solve for u(y). Hint: for steady viscous flow between two plat plates $\frac{\delta P}{\delta x} = \mu \frac{\delta^2 u}{\delta y^2}$ is the governing equation. Remember to derive the above equation. b) Find the layer y=$y_{max}$ where the velocity u is greatest. c) Show a sketch of u(y) indicating $y_{max}$ d) Is $y_{max}$ above or below y=h/2 e) How can your device be used to experimentally determine the viscosity of blood?

Question # 1 What are the main factors responsible for friction losses and pressure drop? Suggest five possible ways to minimize pressure drop. Question # 2 Discuss the applications of Extended Bernoulli Equations in our daily life. Is possible sketch any system and describe their benefits. Question # 3 (Example 6.1 and 6.4) Oil is flowing steadily at a rate of 250 gal/min from tank A to tank B through 3000 ft of 3-in schedule 40 pipe. (Appendix A. 2 shows the dimensions of standard U.S. schedule 40 pipe sizes.) The inside diameter (ID) of 3-in schedule 40 pipe is 3.068 inches. The oil has a density of 62.3 lbm/ft³ and a viscosity of 50 cP. The levels of the free surfaces are the same in both tanks. Tank B is vented to the atmosphere. What is the gauge pressure in tank A required to produce this flow rate? (Note: show all of your calculations) Gas, P=? Same level 3000 ft of 3-inch schedule 40 pipe Tank B Tank A Vent
