Write a paragraph that explains how a droplet of water that falls as rain can move through the atmosphere, the biosphere, the geosphere, and the hydrosphere. be specific as you explain the processes (evaporation, condensation, transpiration) that occur because of interaction between earth’s spheres.
in your response, be sure to…
• give the state of matter that water is in as it moves through earth’s systems
• describe what processes occur to change water from one state of matter to another

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
