    Understanding Closed Feedwater Heaters and Regeneration in the Rankine Cycle

    I have a question on the rankine cycle with a closed feedwater heater. My thermo book says that in an ideal closed feedwater heater, the feedwater is heated to the exit temperature of the extracted steam. I don't really understand this. I know the bleed steam from the turbine is cooled to a...

    Antiderivative of a distance versus time graph

    What does the antiderivative of a distance versus time graph represent? What does the antiderivative of the anitiderivative of a distance versus time graph represent? I think the units would be meters multiplied by seconds. Thanks.

    Find domain of (2+x-x^2)/((x-1)^2)

    I think I figured it out. f(5) would be a local minimum I think I messed up because I choose f(0) as a point to the left of f(5) instead of a point in between 1 and 5. Do you have to include your vertical asymptotes when you are trying to find out if the function is increasing or...

    Find domain of (2+x-x^2)/((x-1)^2)

    f'(5) is neither a minimum or a maximum Why is this a critical number? The graph is increasing to the left of -1 and decreasing to the right of -1. The graph is not changing at 5.

    Find domain of (2+x-x^2)/((x-1)^2)

    I have found a critical number at x=5 but I don't know if that is correct. I have a vertical asymptote at X=1 and a horizontal at y=-1 My derivative of the function is (x-5)/(x-1)^3 but I am not sure f this is right either. I don't know which points to use to tell if it is increasing or...

    Find domain of (2+x-x^2)/((x-1)^2)

    Could someone find the domain, intercepts, asymptotes, critical numbers, local min and max, absolute min and max, concavity, and inflection points of the function: (2+x-x^2)/((x-1)^2) Thank you it would be much appreciated
