(07 MC)Susie wants to make her school dance team and tryouts are in one month. She has always danced for fun, but never on a team. What advice would you give Susie to get ready for her big tryout? O She does not need to practice because she's already a great dancer.
O She should set aside time every day to practice and learn the routines.
O She should become friends with everyone who is currently on the team.
O She should not practice so that she is fresh and well rested for the tryout.

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.
