Question #3: For the following data, a process takes place from State 1 to State 2. Find the properties h, v, u & s at both sides. The initial state is P₁ = 6.5bar Also determine the change in properties h, v, u & s Q# State 1 State 2 Process uh hs x 1 2 V₁ = 0.16m³/kg x=0.8 P₂ = 2.5bar T = 550°C Constant volume Constant pressure

Ms Png works on a piston-cylinder system which contains 0.05 m3 of nitrogen gasinitially at 200 kPa. At this state, a linear spring that has a spring constant of 150kN/m is touching the piston, but no force is exerting on it. Heat is then transferredto the nitrogen gas, causing the piston to rise and to compress the spring until thevolume inside the cylinder increases to 0.25 m3.a) Determine the final pressure inside the cylinder.b) Sketch the system on a P – V diagram.c) Calculate the total work done of the system.d) Deduce the work done against the spring to compress it.Given cross-sectional area of the piston = 0.25 m2Force applied by linear spring, F = kxk = spring constantx = displacement of the piston/spring
