Problem 1 A piston-cylinder system contains a paddle stirrer (a paddle with blades that can stir the contents of the cylinder). The cylinder contains a gas that is initially at 150 kPa and occupies a volume of 0.196 m3 . The piston is unrestrained and has a cross-sectional area of 0.196 m2 . 20 kJ of electrical energy is supplied to the paddle stirrer, resulting in the piston moving up by 0.2 m. During this process, 5.27 kJ of heat...

Problem 1 (Marks 3) Smithfield power station in NSW, Australia operates on 4 gas turbines. Each of the gas turbine unit operates on the regenerative Brayton Cycle between the pressure limits of 100 kPa and 700 kPa. Air enters the compressor at 30°C at a rate of 12.6 kg/s and leaves at 260°C. It is then heated in a regenerator to 400°C by hot combustion gases leaving the turbine. Diesel fuel with heating value of 42,000 kJ/kg is burned in...

A combined cycle gas turbine/vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output of each turbine, and the overall efficiency. --Given Values--...

Q2 Water flows at a rate of 0.08 m''min through a flanged tap with a partially closed gate valve spigot (Fig. Q2). The inner diameter of the pipe at the inlet and outlet is 2 cm and 1.5 cm respectively, and the gauge pressure of the water at inlet is measured to be 90 kPa. The pressure at outlet from the tap is atmospheric. The total mass of the tap assembly plus the water within it is 5.8 kg. (a)...
