Q 3. Superheated steam at the rate of 10 m/min enters a turbine at 350°C and 60 bar through 4.5cm diameter tube line. The turbine operation is adiabatic and the effluent is liquid at 64°C and 5bar which exits
through 8.5 cm diameter tube line. Calculate the heat and work outputs of the turbine in kilo-watts? [8

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
