ME 212 HW 1 Due date : 12.03.2009 (homework must be turned in AT THE BEGINNING OF THE 1st LECTURE HOUR) 1) Consider a regenerative gas-turbine power plant with a single stage of compression and two stages of expansion and a regerenator. The schematic diagram of the establishment can be below and the conditions of the air at various points are given as: P 1 =100 kPa = P 6 = P 7 = P 8 = P 9 , T 1
