can someone help me solve this problem?? Thank you soooooooooooo much!
An evacuated tank of 1 m3 is attached to the exhaust of an air-turbine-driven grinding wheel. Air at atmospheric pressure and 300°K will be allowed to enter the turbine inlet, the pressure drop between the atmosphere and the tank serving to operate the turbine-driven grinder. When the pressure in the originally evacuated tank has risen to the atmospheric, the turbine, of course, stops. a) Assuming the turbine operates in a reversible manner, how many kilowatt-hours of work may be obtained up to the time the pressure in the tank has risen to atmospheric? Consider three cases: (1) tank is adiabatic, turbine is adiabatic; (2) tank is diathermal, turbine is adiabatic. The ideal-gas law may be assumed. b) Determine the air temperature in the tank at the end of the filling process, the entropy change of the universe, and the heat interaction with the environment for each of the cases.
