Use the equation q = (m)(c)(δ t) to calculate the heat gained by the cold water for each trial. show your work using the problem-solving method shown in previous rubrics. the specific heat for water (c) is 4186 j/(kg * c°). cold water beginning temperature - 20 c

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.
