THERMODYNAMICS - Conservation of Mass UPLOAD AND EXPLAIN COMPLETE SOLUTION. Consider steam that enters a turbine at 70 bar, 530oC with a velocity of 64 m/s. The turbine is operating at steady state conditions and the steam leaves the turbine as a dry saturated vapor at 10 bar. The inlet diameter of the turbine is 0.45 m and the outlet diameter is 3.6 m. Determine the mass flow rate of steam through the turbine.
Refrigerant 22 enters the compressor of an air-conditioning unit operating at steady state at 4°C, 5.5 bar and is compressed to 60°C, 14 bar. The refrigerant exiting the com- pressor enters a condenser where energy transfer to air as a separate stream occurs and the refrigerant exits as a liquid at 14 bar, 32°C. Air enters the condenser at 27°C, 1 bar with a volumetric flow rate of 20.25 mº/min and exits at 43°C. Neglecting stray heat transfer and kinetic and potential energy effects, and assuming ideal gas behavior for the air, determine (a) the mass flow rate of refrigerant, in kg/min, and (b) the compressor power, in kilowatt.

The figure shows data for a portion of the ducting in a ventilation system operating at steady state. The ducts are well insulated and the pressure is very nearly 1 atm throughout. The volumetric flow rate entering at state 2 is AV2 = 4000 ft3/min. Assume the ideal gas model for air with cp = 0.24 Btu/lb·oR and ignore kinetic and potential energy effects.

Steam enters a turbine at 30 bar, 300°C (u = 2750 kJ/kg, h = 2993 kJ/kg) and exits the condenser as saturated liquid at 15 kPa (u = 225 kJ/kg. h = 226 kJ/kg). Heat loss to the surrounding is 50kJ/kg of steam flowing through the turbine. Neglecting changes in kinetic energy and potential energy, what is the work output of the turbine (in kJ/kg of steam)?
An industrial process discharges 75.3 kg/s of gaseous combustion products at 204°C, 100 kPa (properties at state 1). As shown in the figure, a proposed system for utilizing the combustion products combines a heat-recovery steam generator with a well-insulated turbine. At steady state, combustion products exit the steam generator at 130°C, 100 kPa, and a separate stream of water enters at 350 kPa, 46°C with a mass flow rate of 150 kg/min. At the exit of the turbine, the pressure is 7.5 kPa and the quality is 88%. Heat is lost from the steam generator at a rate of 93600 kJ/h. The changes in kinetic and potential energies of the flowing streams can be ignored as can the pressure drop for the water flowing through the steam generator. The combustion products can be modeled as air acting as an ideal gas with constant specific heats of Cv= 0.718 kJ/kg-K and Cp=1.005 kJ/kg-K. Use Rair = 0.287 kJ/kg-K. Also, for the compressed liquid, assume the substance is a saturated liquid at the given…

5Air enters a two-stage compressor operating at steady state at 520°R, 14 lbf/in.2 The overall pressure ratio across the stages is 12 and each stage operates isentropically. Intercooling occurs at constant pressure at the value that minimizes compressor work input, with air exiting the intercooler at 520°R. When the temperature of the air entering each compressor stage is the same, the minimum total compressor work input per unit of mass flowing occurs when the pressure ratio is the same across each stage.Assuming ideal gas behavior, with k = 1.4, determine the work per unit mass of air flowing for the two-stage compressor, in Btu per lb of air flowing.

Need Help going through the process on how to solve this problem. May accidentally be asking this a second time, because the first time I asked it, it didn't show as a pending problem. Steam expands adiabatically through a turbine at steady state. The entering stream is at 750 lbf/in^2, 750°F, and the exiting stream is a saturated vapor at 10 lbf/in^2. Kinetic and potential energy effects are negligible. a. How much work per lb of flow does the turbine produce, in Btu/lbm? b. If the turbine produces 3000 kW of output power, determine the mass flow rate of steam in kg/s. c. If this process were isentropic, the existing stream would no longer be a saturated vapor. Determine the final quality of steam in that case. d. Determine the isentropic turbine efficiency.
