Answer #1

Please note that vertical line from point A is drawn since the process is isentopic meaning the entropy remains constant during expansion.

Since I have used Mollier Chart in SI units and then converted the answer to fps, the answer may not match exactly. However, I have tried to focus on the steps which can be used for other similar problems.

For any further clarification or feedback please reply in the comments.

United flight 15 from New York’s JFK to San Francisco uses a Boeing 757-200 with 182 seats. Because some people with reservations don’t show up, United can overbook by accepting more than 182 reservations. If the flight is not overbooked, the airline will lose revenue due to empty seats, but if too many seats are sold and some passengers are denied seats, the airline loses money from the compensation that must be given to bumped passengers. Assume that there is...

A state legislator wants to determine whether his voters' performance rating (0 - 100) has changed from last year to this year. The following table shows the legislator's performance from the same ten randomly selected voters for last year and this year. Use this data to find the 99% confidence interval for the true difference between the population means. Let d=(this year's rating)−(last year's rating). Assume that the populations of voters' performance ratings are normally distributed for both this year...
