Two point sources produce waves of the same wavelength that are in phase. at a point midway between the sources, you would expect to observea)constructive or destructive interference depending on the wavelength. b)destructive interferencec)no interferenced)constructive interferencee)alternating constructive and destructive interference interference

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.
