1)A baseball stadium can hold a maximum of 55000 spectators. Before the gates open there are only 200 stadium personnel in the stadium. When the gates open there are 500 times more spectators than media personnel that enter the stadium. There are 50 baseball players that enter the stadium. During the game one-fourth of the spectators leave. There are 30000 spectators at the end of the game. No players stadium personnel or media personnel leave during the game. Using the accounting principle calculate the total number of people in the stadium at the end of the game. [hint: if you define variables for some of the quantities involved in the problem you can translate the word relationships into equations among these variables.]2)Fuel oil is used to fire a small power plant to generate electricity. The fuel oil fires a boiler that generates steam which in turn drives a steam turbine connected to an electric generator. The power plant requires 160 lbm/h of fuel oil to steadily generate electrical energy at the rate of 290 kW. In addition the combustion of the fuel requires 15.8 lbm of air for each pound-mass of fuel supplied to the power plant.ElectricityPower PlantFuelAirExhaustAsh Use the accounting concept clearly stating all assumptions and determine:the rate at which air must be supplied to the power plant and the rate at which exhaust and ash (combined) are produced in units of lbm/h.the amount of fuel required and the amount of exhaust and ash (combined) produced in lbm if the plant operates continuously for 24 hours.
