In a Rankine cycle, steam leaves the boiler at 400 C and 5 MPa. The condenser pressure
Question:
In a Rankine cycle, steam leaves the boiler at 400° C and 5 MPa. The condenser pressure is 0.01 MPa. The water entering the pump is saturated. Determine the first-law thermal efficiency and compare it to that of a Carnot cycle operating between the same temperature extremes.

I have experience teaching math, science, and English to students of all ages. I have also worked as a tutor in a college setting, helping students with their homework and preparing them for exams.
I believe that tutoring is a great way to help students learn. It allows students to get one-on-one help with their studies, and it gives them the chance to ask questions and get immediate feedback. Tutoring can also be tailored to the individual needs of the student, which is why I believe it is so effective.
I have seen firsthand how tutoring can help students improve their grades and confidence. I have also seen how it can help students who are struggling with a particular subject. I believe that tutoring is a great way to help students learn and succeed in school.
