In my garage, i have a tank filled with compressed air, an ideal gas. the gas is at ‘room temperature,’ 25 °c and a gauge pressure of p1= 130 psi (896 kpa).the compressed air tank has a volume ∀1(given in .xls file). i allow the gas to flow through a small turbine (great yard sale [10 pts]if heat transfer with the surroundings is negligible, what is the maximum theoretical work푾풎풂풙i can extract if the turbine vents to an initially evacuated chamber ofvolume ∀2(given in .xls file)? **take atmospheric pressure to be 푃'()=101 kpa and the gas to have constant specific heats, cp= 1.004 kj/kg-k, k= 1.4

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
