Q2. A gas turbine with air as the working fluid has two ideal turbine sections, the first of which drives the ideal compressor, with the second producing the power output. The compressor input is at 290 K, 100 kPa, and the exit is at 450 kPa. A fraction of flow, x, bypasses the burner and the rest goes through the burner where 1200 kJ/kg is added by combustion. The two flows then mix before entering the first turbine and continue through the second turbine, with exhaust at 100 kPa. If the mixing should result in a temperature of 1000 K into the first turbine find the fraction x. Find the required pressure and temperature into the second turbine and its specific power output. Take C,-1.004 and 1.13 kJ/kg.K for cold and hot air respectively.

15.16. Files & More (F&M), a manufacturer of office equipment, is introducing a new product, the BUNGEE desk chair, made from elastic webbing that provides both comfort and support. The materials that go into the chair are shown below. a. Construct a product structure diagram that reflects how the product is assembled. b. Convert the product structure diagram into a multilevel indented bill of material. c. F&M is trying to decide how much of the chair to assemble for the customer prior to shipping. Recommend a preassembly strategy that would allow easy assembly for the customer, and document it with a revised multilevel indented bill of material.
