I need the answer as soon as possible
1.3 0-05 m3 of a gas at 6-9 bar expand reversibly in a cylinder behind a piston according to the law pu²-2=constant until the volume is 0-08 mº. Calculate the work done by the gas and sketch the process on a p-v diagram. N 1.4 1 kg of a fluid expands reversibly according to a linear law from 4-2 bar to i-4 bar. The initial and final volumes are 0-004 m3 and (15 300 N m) 0-02 m respectively. The fluid is then cooled reversibly at constant pressure and finally compressed reversibly according to a law pv=constant back to the initial conditions of 4-2 bar and 0-004 m°. Calculate the work done in each process stating whether it is done on or by the fiuid and calculate the net work of the cycle. Sketch the cycle on a p-v diagram. 1.5 0-09 m of a fluid at 0-7 bar are compressed reversibly to a pres- sure of 3-5 bar according to a law pu"=constant. The fluid is then heated reversibly at a constant volume until the pressure is 4 bar; the specific volume is then 0-5 m/kg. A reversible expansion according to a law pu =constant restores the fluid to its initial state. Calculate the mass of fluid present, the value of n in the first process, and the net work done on or by the fluid in the cycle. Sketch the cycle on a p-v diagram. (4480; --1120; - 1845; 1515 N m) (0-0753 kg; 1-85; 676 N m)
