A driver followed a man with a surfboard strapped on top. The driver claims that the van stopped so quickly that the surfboard flew backward, hitting his car and causing damage. He wants the driver of the van to pay for damage to his vehicle and medical costs. You are the judge in the case. Use Newton's laws of motion to write a judgment in the case.

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.
