Kasey Reynolds 1 Final Exam: Starbucks Case Study External Analysis The general environment of the coffee industry is affected by many different factors. Social forces include factors such as lifestyle and cultural tastes. From their first store in Seattle‚ WA Starbucks learned that customers wanted a place to sit down and have a cup of coffee‚ while other customers wanted to get coffee quickly by utilizing a drive-thru. Both of these options have been added to appeal to a larger customer base

However‚ when a Reynolds number reach about 300‚000‚ and the sphere is the largest one; for this case‚ the drag coefficient drops abruptly. We also found that for the same wind speed‚ the larger sphere has larger Reynolds number. The figure below illustrates the relationship between Reynolds number and drag coefficient. The results obtained from this experiment also tend to show the same relationship. Stoke’s Theory predicts that the drag coefficient decreases as the Reynolds Number less than

Osborne Reynolds Demonstration Sayed abbas Mohamed 20104762 03 1. Objective: To reproduce the classical experiments conducted by Professor Osborne Reynolds concerning fluid flow condition. 2. Theory: Reynolds number‚ Re is the internationally recognized criterion denoting fluid flow condition. “ Re = 4Q/ πvd ” Osborn Reynolds determined that values of Re could be assigned to define the transition from laminar to turbulent flow. 3. Apparatus: -Osborne Reynolds apparatus

velocity of the flow and g is gravity. Flow Rate The flow rate in a pipe can also be calculated using (eq 2) In this case u is used for velocity‚ Q as volume flow rate and A‚ cross sectional area of the pipe. Reynold’s Number In fluids‚ the Reynolds number (Re) is a dimensionless number which gives a measure of the ratio of inertial forces to viscous forces. The Reynold’s Number is also used to classify laminar and turbulent flow values. When working with pipes that have different

Sacrifices Summary and Characterization The story Sacrifices by R.J Ellory is about Kathleen Reynolds who works as a cop at the Fairfax County Homocide Division. Kathleen Reynolds has given up both husband‚ kids‚ her family and holidays‚ for her career. Later on in the text we are introduced to a woman named Bitsy whose mother is diagnosed with terminal cancer. Bitsy can’t bear seeing her mother in agony‚ and therefore she overdoses the morphine that is used to relieve her mother’s pain‚ with the

smooth pipe shows that there are existence of laminar and transitional flows as stated in Graph 2.0 and Graph 2.1. It is proven that the higher velocity along the smooth bore pipe‚ the higher is the head loss of water. As shown in Table 3.0‚ when the Reynolds’ number increases‚ the value of pipe coefficient friction‚ f decreases along the decreasing stead laminar line. On top of that‚ there are energy loss from the water to the surface of the pipe and therefore‚ the temperature increases when velocity
