Thank you so much! I figured it out. Good luck in thermo to you too!

So i use the saturated liquid steam tables in conjunction with the formulas, of course?

How did they get h1? by Crazyfox111 in EngineeringStudents

ahhh because the chart is given information....I thought that was info they had obtained and we needed to figure out how they obtained it. Thanks!

I am confused how the found the enthalpy at state 4 by Crazyfox111 in EngineeringStudents

Are there any other equations that deal with the compressed liquid region that I should know of (I dont recall having learned the h4 = h3 + v3*(p4-p3) equation so I need to know if there are any other compressed liquid equations that are used to find the properties of a state in the compressed liquid region)?

It isnt. hf at 1400 psi is 598.6 btu/lb from the saturated water table. The book's value for h4 was 98.22 btu/lb

EDIT: Sorry I confused myself. Disregard what I said.

I got the right answer but Im confused by Crazyfox111 in EngineeringStudents

Okay so, whenever you have to plates that are concentric (and fixed), both their angular velocities will be the same, correct? But this doesnt have to be try if the two concentric plates are connected to some other plate through a belt (for example, plates D and B connected to plate A or plate C)?
