- Four methods for controlling head pressure in an air-cooled condenser are ______, ______, _______, andWelded ______sealed compressors are normally used in household refrigerators.Steam enters the high-pressure turbine at 150bar and 550c and low pressure turbine at 40bar and 550c .the condensor pressure is 0.1bar using mollier diagram find 1.the dryness fraction at the end of low pressure turbine 2.efficieny 3.steam rate 4.heat rate 5.work ratio
- I need help on the following question: The vapour compression cycle (picture provided), utilises the refrigerant R134a flowing at 0.05 kg s-1. Assuming that the compression is adiabatic and reversible. If the actual input power to the compressor is 2 kW, then: 1. You need to determine the theoretical input power to the compressor and the heat transfer (Φ) to theevaporator. Take the enthalpies h1, h2, and h3 to be 238.41, 263.68 and 81.5 kJ kg-1 (use the 'NH3 Refrigeration Table' where you can find online). 2. You need to determine the coefficient of performance based on your answer to the previous question (1). 3. You need to determine the compressors mechanical efficiency.Steam is produced for an ideal turbine at a pressure of 3.0MPa. The condenser pressure is 2.0kPa. The heat added per kilogram is 2750kJ. Neglecting pump work, determine the thermal efficiency.The enthalpy entering the turbine of a geothermal power plant is 2750 KJ/kg and ,ass rate of 1 Kg/sec. The turbine brake power is 1000 KW condenser outlet has enthalpy of 210 KJ/kg. If temperature rise of cooling water in condenser is 8, what is the mass of cooling water requirement?
- rankine cycle, the pressure and temperature entering the turbine is 1800 kpa and 380 degrees celsius and the pressure leaving the turbine is 20 kpa, the quality of steam entering the condenser is 90%. what is the turbine work in kj/kg at 1.8 mpa and 380 degrees celsiusAn ideal double-reheat Steam turbine receives 300,000 kg/hr of steam at 10 Mpa and 400°C. After expansion from high pressure turbine shell, it is reheated twice from saturated vapor condition back to its initial temperature. The steam entering the condenser is 97% dry. Determine: a.) Engine work b.) Engine thermal efficiency c.) Steam rateSteam is generated at 5.15 Mpa and 525C and condensation occurs at 0.127 Mpa. Considering that a Rankine cycle occurs between the same limits, determine the QA, QR, Wnet, cycle efficiency, engine efficiency and heat rate. What mass flow rate is required for a net output of 25000 kW?
- A dry and saturated steam supplied in a power plant is at 1500 kPa. Determine theefficiencies of Carnot and Rankine cycle if the pressure at the condenser is at 40 kPa,neglecting pump work.A steam power plant operating on regenerative cycle, as illustrated in Fig 8.5, includs just one feedwater heater. Steam enters the turbine at 650 psia and 900oF and exhaust at 1 psia. Steam for the feedwater heater is extracted from the turbine at 50 psia, and in condensing raises the temperature of the feedwater to within 11oF of its condensation temperature at 50 psia. If the turbine and pump efficiencies are both 0,78, what is the thermal efficiency of the cycle and what fraction of the steam entering the turbine is extracted for the feedwater heater?Condenser a steam power plant that operates on a simple ideal ranking cycle and has a net power output of 22MW. Steam enters the turbine at 7Mpa and 450.05°C and is cooled in the condenser at a pressure of 10kpa by running cooling water from a lake through the tubes of the condenser at rate of 1750 kg/s. Determine the mess flow rates of steam through the steam turbine assuming that the cp of superheated steam is 2.9593kJ/kg.K.
