Refrigerant-134a is in an insulated canister with temperature 25 C. There is a partition in the canister so the refrigerant is a saturated liquid and takes up 1/100 of the volume of the canister. The rest of the volume is evacuated. When the canister is activated by squeezing (no work done activating) the partition breaks and the refrigerant fills the total volume. Final pressure is 100 kPa. a.) What are two assumptions needed for the problem? What properties are needed to solve part b.) and c.) b.)

Steam flows into a turbine at the rate of 10 kg/s and 10 kW of heat are lost from the turbine. Ignoring elevation and kinetic energy effects, calculate the power output from the turbine.Note : h1 = 2739 kJ /kg and h2 = 2300.5 kJ / kg CHOICES: A. 4605 kW B. 4973 kW C. 4375 kW D. 4000 kW
b) Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change. Steam out Gas out Hot gas in Liquid water in Fig 2. Schematic of the steam generator in Q1.b.
