Aloaded garbage truck has low acceleration. it takes 10 seconds to go from 0 km/h to 100 km/h. what is the acceleration of the garbage truck? how much slower is the acceleration of the garbage truck compared to the acceleration of the sports car in figure 4.18?

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.
