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.(iii) What is the exit velocity of the steam?

H₂O Po 4.23 Two kilograms of water are contained in a piston/cylinder (Fig. P4.23) with a massless piston loaded with a linear spring and the outside atmosphere. Initially the spring force is zero and P₁ = P₁ = 100 kPa with a volume of 0.2 m³. If the piston just hits the upper stops the volume is 0.8 m³ and T = 600°C. Heat is now added until the pressure reaches 1.2 MPa. Find the final temperature, show the P-V dia- gram and find the work done during the process.

A fixed-mass system contains mass, m = 1.0 kg of air. A thermodynamic process occurs from state one to state two, where T₁ = 300 °K, P₁ = 100 kPa; T₂ = 2700 °K, P₂ = 204.9953251 kPa. Determine S₂ - S₁ = m (S₂-S₁) in kJ / °K. Note: You are required to assume constant specific heats in this problem, with Cpo = 1.004 kJ/(°K * kg); for air, the gas constant is R = 0.287 kJ/(°K * kg).
20 g of air undergoes a closed cycle, illustrated in Figure Q2, which consists of the following 3 processes: 1-2 Constant pressure heat rejection. 2-3 Constant volume heat addition. 3-1 Isothermal expansion back to the original conditions.

A piston-cylinder assembly contains a mystery substance that undergoes a series of processes. Process 1-->2: Constant pressure process at 5bar from v1=.07m3/kg to v2=.12m3/kg Process 2->3: Constant volume process to saturated vapor Process 3->4: Constant temperature process to quality of 50% Process 4->5: Constant volume process to 5bar Sketch the processes on Pt, Pv, and Tv, plots. Lable the axes including property values; use closed dots to show the states, use solid lines to connect the states, add number and arrows to make clear the states numbers and process directions. Could this be considered a thermodynamic cycle? Why or why not?

Air expands adiabatically in a piston-cylinder assembly from an initial state where p₁ = 100 lbf/in.², v₁ = 3.704 ft³/lb, and T₁ = 1000 °R, to a final state where p₂ = 30 lbf/in.²2 The process is polytropic with n = 1.4. The change in specific internal energy, in Btu/lb, can be expressed in terms of temperature change as Au = (0.171)(T₂ - T₁). Determine the final temperature, in °R. Kinetic and potential energy effects can be neglected. T₂ = i °R
