There is no air resistance on the moon, so when Neil Armstrong dropped a
hammer all of the potential energy turned into kinetic energy. If Neil was 12
feet tall instead of 6 feet, would the hammer be moving faster or slower
just before hitting the ground? Why?

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.
