Steam enters an adiabatic turbine at 800 K and 6.0 MPa and leaves at 700 K and
Question:
Steam enters an adiabatic turbine at 800 K and 6.0 MPa and leaves at 700 K and 3.0 MPa. The mass flow rate is 450 kg/hr. The potential and kinetic energies can be neglected. Determine the following:
A. The power delivered (kW)
B. The ratio of the outlet flow area to the inlet flow area needed to keep the exit velocity equal to the inlet velocity

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.
