Problem 3 - The School or Aeronautics is doing some weather evaluations using a helium-filledspherical balloon with a radius of 12 inches. The balloon and associated instrumentation weigh0.1 lbf. Determine the terminal ascent velocity of the balloon if the air temperature is 60°F.The terminal ascent velocity is based on when the balloon's velocity is constant (no4VolumeπρSphere 3acceleration). The volume of the balloon iswhere r is the radius. Use atemperature of 60°F to determine the air properties. The problem is an iterative problem butlimit the number of iterations to 2 and make sure you explain the solution process and theequations required. Although not required creating a free-body diagram may make solving theproblem easier. Do not spend time trying to create the final numerical solution.

You serve as the president of XYZ corporation, which is an energy intensive manufacturing operation. You have four boilers to produce steam and electricity for your operations. One is a semi-suspension fired boiler with a capacity of 100 tons of coal per hour. The boiler can also burn supplemental fuel such as coconut or macadamia nut shells. The other three boilers arc peaking units and burn fuel oil. The City of Podunk has approached you about the possibility of burning solid waste as a supplemental fuel. As the president of the XYZ Corporation, you need to develop answers to many political, social, and technical questions before you make a commitment to the city. a. What specific questions would you ask your own power plant engineer about the possibility of accepting Podunk’s MSW? b. What specific additional data would you need from the city before you discuss this further?
