    Designing coal feeders for a powerplant.

    Thanks, that makes sense, but how do I get the enthalpy after the hp turbine or after the lp turbines. Am I supposed to be working from somewhere else in the system? My other idea is maybe tabulating the solutions to the system at different massflows until I find a value where everything...

    Designing coal feeders for a powerplant.

    Here is a crude drawing I made of the problem with some of the relevant information. I was wondering if anyone knows the typical state of the exhaust steam exiting a High Pressure turbine before it goes to the reheater. Is it superheated or saturated? How do I find the enthalpy there? I have...

    Designing coal feeders for a powerplant.

    Good tip. I am currently drawing the system and writing the information and the useful equations I know for each component.

    Designing coal feeders for a powerplant.

    I was given this problem as an excercise in thermodynamics and to better understand powerplant systems. I am having difficulties because as a civil engineering student I haven't taken a lot of thermodynamics. The one course I did take was several semesters ago and wasn't that advanced...

    Thermo/Fluids Research Paper Idea

    I am a sophomore engineering student taking a thermodynamics/fluid mechanics course right now. We have to write a short 4 page research paper on a topic of our choosing, that deals with thermodynamics and/or fluid mechanics. I am looking for ideas on a good topic, keeping in mind that I have to...

    Terminal Velocity of a Concrete Sphere

    Thanks, that website is awesome. Can someone tell me what the exp means in the impact and velocity equations. It turns out the concrete sphere fell from a height low enough that it never reached terminal velocity. When I was first calculating the time and velocity at various heights I used the...

    Terminal Velocity of a Concrete Sphere

    Thanks a lot! I'm sure it will suffice.

    Terminal Velocity of a Concrete Sphere

    Homework Statement I need to find the approximate terminal velocity of a baseball shaped concrete sphere and what distance it would take to reach that terminal velocity if dropped on Earth under normal weather conditions. I have found that a baseball made of concrete would have a mass of...
