#Easy power 8.0 windows 8#
Windows 8 was released to a mixed critical reception. Windows 8 is the first version of Windows to support the ARM architecture, under the Windows RT branding. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware, to prevent malware from infecting the boot process. Windows 8 added support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Many of these features were adoptions from Windows Phone. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language and the Start screen (which displays programs and dynamically updated content on a grid of tiles), a new platform for developing " apps" with an emphasis on touchscreen input, integration with online services (including the ability to synchronize apps and settings between devices), and Windows Store, an online distribution for downloading and purchasing new software, and a new keyboard shortcut for screenshots.

Windows 8 introduced major changes to the operating system's platform and user interface intended to improve its user experience on tablets, where Windows was now competing with mobile operating systems, including Android and iOS.

Refrigerant 134a is in an ideal Rankine cycle with refrigerant entering the turbine at 1.5 MPa, 101Īnd saturated liquid leaving the condenser at 800 kPa.ĭetermine (a) the rate of heat transfer to the working fluid passing through the steam generator of the steam cycle, Liquid at 100 kPa, which is combined with the return flow from the process, at 100 kPa and 65 The condensate leaves the heat exchanger as saturated Serves as the boiler for the refrigerant cycle and the condenser of the steam cycle. The rest of the stream passes through a heat exchanger, which Half of the flow is extracted at 150 kPa and is used for industrial process heating.
Superheated vapor enters the turbine with a mass flow rate of 5 kg/s at 4 MPa, 470 Water and refrigerant R-134a are the working fluids in a binary cycle used for cogeneration of power and process steam. What would the thermal efficiency be if air were used as working fluid for the gas phase? Water enters the pump as saturatedĭetermine (a) the thermal efficiency of the combined cycle, (b) the mass flow rates of steam and The steam exits the turbine at a quality of 0.9. Vapor power cycle, and expands to the condenser at a pressure of 7 kPa. Saturated vapor at 8 MPa exits the heat exchanger which is superheated to 425 The mass flow rate of the gas is 100 kg/s. The turbine has an isentropic efficiency of 80%. Helium expands through the turbine to a pressure of 1.4 MPa.
The conditions at the inlet to the turbineĬ.
The isentropic efficiency of the compressor is 80%. Helium enters the compressor of the gas turbine at 1.4 MPa,ģ50 K and is compressed to 5.5 MPa. If the working fluid experiences no irreversibilities as it passes through the turbines, pumps, steam generator, reheater and condenser, determine (a) the thermal efficiency of the cycleĪnd (b) the mass flow rate of steam entering the first turbine.Ĭonsider a combined cycle power plant using helium and water as the working fluids. There is no stray heat transfer from any component to its surroundings. The net power output of the cycle is 100 MW. The steam exiting the open feedwater heater is saturated liquid at 0.3 MPa. Steam extracted from second turbine at 0.3 MPa is also fed into the open feedwater heater, which operates at 0.3 MPa. The condensate is trapped into the open feedwater heater. Feedwater leaves the closed heater at 205Ĭ, 10 MPa and condensate exits as saturated liquid at 2 MPa. Steam is extracted from the first turbine at 2 MPa and fed to the closed feedwater heater. The steam is reheated to 440Ĭ before entering the second turbine, where it expands to the condenserĪt a pressure of 0.007 MPa. Steam enters the first turbine at 10 MPa, 500Ĭ and expands to 0.8 MPa. Consider a reheat-regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater.
