3. Ideal gas in a cylinder is heated at constant volume from a temperature of 600°C to a temperature of 1000°C, and then further heated at constant pressure from 1000°C

to 1300°C. The change in specific entropy in the first process is 0.283 KJ/kgK. After being heated the gas expands isentropically to fifteen times its initial volume and a temperature of 306 C. a. Sketch the processes on P-V and T-S diagrams b. Find the index of isentropic expansion c. Find Cv, Cp,R d. Find the total specific work е. Find the total specific heat f. Find the total change in specific entropy
