A steam turbine receives steam from 2 boilers. The first flow is 10 kg/s at 6 MPa (60 bar), 600°C. The second flow is 17 kg/s at 1500 kPa (15 bar), 400°C. The exit flow is at 100 kPa (1 bar), with a quality of 85%. Determine the power output of this turbine (in kW).

the initial mass (m1) in (kg) is A rigid 0.15 m³ tank contains air at 0.8 MPa, 200°C. A valve on the tank is now opened and air flows out until the pressure drops to 100 kPa. During this process, heat is transferred between tank and surrounding, such that when the valve is closed, the temperature inside the tank is 60°C. me valve Tank Air, V-0.15 m² P₁=0.8 MPa, T₁= 200 C P₂ = 100 kPa > T₂ = 60°C

2. A steady stream of steam passes through a turbine. The steam inlet conditions are 10MPa, 450°C and 80m/s and at the outlet they are 10kPa, 92% quality and 50m/s. The mass flow of the steam is 12 kg/s. Determine a) the change in kinetic energy, b) the power developed by the turbine, and c) the area of ​​the turbine inlet.

As shown in the figure below, water behind a dam enters an intake pipe at a pressure of 24 psia and velocity of 5 ft/s, flows through a hydraulic turbine-generator, and exits at a point z1 = 120ft below the intake at 19 psia, 45 ft/s, and a specific volume of 0.01602 ft/lb. The diameter of the exit pipe is 5 ft and the local acceleration of gravity is 32.2 ft/s?.

Q1) In a turbine-compressor system, the steam enter the adiabatic turbine at 3 MPa, 500°C, and velocity 50 m/s. The exit condition of the steam are 20 kPa, ve = 46.231962 m³ /kg, and velocity 40 m/s. The turbine operate insulated compressor to deliver 120 kPa, 47°C, and velocity 10 m/s of air to the high pressure at 500K. determine the compressor outlet velocity. Steam Turbine Compressor Air
