Air flows through a tube that has a throttling valve in it. if the tube is perfectly insulated perform a thermodynamic analysis to determine how much entropy, in any , is generated in this throttling prosses. you may assume that the specific heats of the air are constant. the inlet temprature is 300K and the inlet pressre is10 bar. the exit pressre is 1.0(one) bar. m= 1kg/s.
