Required information Problem 05.038 - Diffuser flow DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air at 80 kPa, 27°C, and 220 m/s enters a diffuser at a rate of 2.5 kg/s and leaves at 42°C. The exit area of the diffuser is 430 cm2. The air is estimated to lose heat at a rate of 18 kJ/s during this process. The gas constant of air is 0.287 kPa-m3/kg-K. The enthalpies are m = 300.19 kJ/kg and h2 = 315.27 kJ/kg. Problem 05.038.a - Diffuser flow Determine the exit velocity of the air. (You must provide an answer before moving on to the next part.) The exit velocity of the air is m/s.

A 5-feet diameter Chimney is designed to handle a flue gas produced in a steam power plant at a rate of 17 lb/s. The barometric pressure is 29.92-inch Hg. Outside air enters the combustion chamber at 90 F. The average temperature of the flue gas inside the Chimney is 572 F and its molecular weight is 30. Cv = 0.35, Rair = 53.342 ft-lb/lb-R. Calculate: 5. The total draft, feet of air. 6. The height of the Chimney, feet
You are designing a system to mix fuel and air prior to ignition in an engine. Do you want the flow to be laminar or turbulent? Why?
Task 2 Your second customer wants to determine the dissipated electrical power by a personal computer, which has a fan that draws 5 L/s of air at 101.325 kPa and 21°C through the box containing the CPU and other components. After that air leaves at 101.325 kPa and 30 °C. Figure 2: Schematic for task 2. You must follow the following parts to do your task: Part 1 Derive the steady flow energy equation (SFEE) from the first principles. You are required to show all the steps in deriving the SFEE and using both the principles of mass and energy conversation. Part 2 Produce specific steady state energy equation (SFEE) by stating all the stated assumption in this equipment in order to be used in later stages without further analysis. Then calculate the pump power. Part 3 Apply the short form to determine the dissipated electrical power by the personal computer.
