In a combustion turbine using natural gas as the fuel, air enters the compressor at 98 kPa and 300 "K. The pressure ratio in the compressor is 8 and the isentropic efficiency of the compressor is 85%. The outlet temperature of the combustion chamber is 1200 K. The pressure drops by 4 percent in the combustion chamber. The exit pressure of the turbine is 102 kPa and the isentropic efficiency of the turbine is 90%. Find: a) The exit temperature...

Air stored underground at 500 psia and 200 deg.F is first heated by natural gas combustion to 2,340 deg.F at constant pressure, then expanded in an 89% efficient turbine to atmospheric (14.7 psia) pressure. Part of the work of the turbine is used to compress ambient air at 70 deg.F and 14.7 psia to store it underground with an 85% efficient compressor. The air that is stored underground loses heat to the surroundings. The turbine powers an electric generator that...

Natural gas has a chemical formula of C1.12H4. Using this formula, write a balanced equation, one for each fuel, for complete combustion in air. * Please note that Natural Gas' chem formula has a decimal as a subscript C (subscript: 1.12)H (subscript 4). I can not figure out how to work through this.

Natural Gas burns according to the chemical reaction CHs:20 COHeat where Heat 15MWh/ton of CH4 burned. Atomic weights are 12 for C,I for H, and 16 for O. Consider a Combined Cycle Natural Gas Turbine (CCGT) electricity generating unit with capacity 1000MW that converts heat to Electricity at an efficiency of 60%. Consider also an algae-based photosynthesis process that converts COn from the stack of the CCGT to CHnat the rate of 10 tons of CHe per acre per year....

An Otto engine is operating with natural gas which can be approximated as an ideal gas. Assuming the engine is at standard condition (25°C, 1 atm) before the compression process. Also, temperature of the Otto cycle after the combustion process is 1500 K. (a) Assuming compression ratio of the Otto engine as 8, 9 and 10, determine the corresponding temperatures of the natural gas-air mixture (natural gas with 100% excess air) after the compression. (b) Determine the thermal energy release...
