CHAPTER 2 NUMERICAL|FIND TOTAL WORK DONE|THERMODYNAMICS|SPRING TYPE NUMERICAL|PART-17|SHOBHA PANDIT
THIS IS THE SOLUTION OF NUMERICAL;
#A gas enclosed by a piston shown in the figure starts to expand due to heating. The initial movement of 0.2 m is restrained by a fixed mass of 30 kg and the final 0.05 m is restrained both by the mass and a spring of stiffness 10 kN/m. The cross sectional area of the piston is 0.15 m^2 and the atmospheric pressure is 100 kPa.
(a) Neglecting the mass of the spring and the piston sketch a P-V diagram of the process.
(b) Calculate the work during the initial 0.2 m movement.
(c) Calculate the total work done.( Take g=9.81 m/ s^2)
