C) the processes are done reversibly
E) Two idiabatic processes where there is no heat loss. Since it is also reversible, so this becomes isentropic process
F) no loss in form of entropy, because process are assumed isentropic.

T9D.3 In this problem, you will calculate the efficiency of a Carnot engine without referring to entropy (a) Consider the isothermal expansion in step 1 of the Car- not cycle. Because the temperature of the gas remains constant, work energy that flows out of the gas as it expands must be balanced by the heat energy flowing into the gas. Use this and equation T7.10 for the work done in an isothermal expansion to show that (T9.16) (b) In a...

please answer all parts (a,b, and c)
In class we showed that for a Carnot cycle for an ideal gas (Lecture 8, page 10), the following identity follows: Sigmai qi/Ti = q1/T1 + q2/T2 = 0, Where qi, is the (reversible) heat associated with each isothermal step. As we shall see next week, we will be able to identify each of these terms as entropy contributions, DeltaSi = qi/Ti, such that they add up to zero in a cycle, giving...

//*we need to do it with C programming *// ENGR 200 P5: CARNOT EFFICIENCY OF POWER PLANTS (if statements, loops) DUE: . U.S. Central Time POINTS: 55 INTRODUCTION: In thermodynamics, energy can be neither created nor destroyed (1st law): it is either converted to usable work or lost as waste heat. The second law of thermodynamics states that the total entropy (disorder) of a system will never decrease over time; that is, systems can only be at constant entropy or...
