A 3\"-diameter, 5\"-long gas-piston assembly contains air at STP.(STP: Standard Temperature and Pressure conditions, 300K and 1 atm.At these conditions the air density is approximately 1.2kg/m3.)Calculate the necessary piston displacement in order to increasethe pressure to 45 atm (typical of a diesel engine) varyinglinearly with displacement (i.e. the pressure varies linearly withdisplacement) during an adiabatic compression that will increasethe gas’ internal energy by 1.2kJ.
