ARGON GAS flows steadily through a well-insulated turbine at the conditions shown below. Some of the flow exits at an intermediate pressure at (2), as shown. The remainder of the gas exits at low pressure at (3). The flow areas all differ. The inlet mass flow rate at state (1) is 6.0 kg/s. Given: A3 = 3 A2 (Flow area at (3) is 3 times the flow area at (2).)
