Plate Heat Exchanger - Flow Distribution and Heat Transfer Equation

Flow Distribution and Heat Transfer Equation

Design calculations of a plate heat exhchanger include flow distribution and pressure drop and heat transfer. The former is an issue of Flow distribution in manifolds. The total rate of heat transfer between the hot and cold fluids passing through a plate heat exchanger may be expressed as: Q = UA∆Tm where U is the overall heat transfer coefficient, A is the total plate area, and ∆Tm is the temperature difference. U is dependent upon the heat transfer coefficients in the hot and cold streams.

Famous quotes containing the words flow, distribution, heat, transfer and/or equation:

    On the idle hill of summer,
    Sleepy with the flow of streams,
    —A.E. (Alfred Edward)

    There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.
    Ralph Waldo Emerson (1803–1882)

    The hotel was once where things coalesced, where you could meet both townspeople and travelers. Not so in a motel. No matter how you build it, the motel remains the haunt of the quick and dirty, where the only locals are Chamber of Commerce boys every fourth Thursday. Who ever heard the returning traveler exclaim over one of the great motels of the world he stayed in? Motels can be big, but never grand.
    —William Least Heat Moon [William Trogdon] (b. 1939)

    No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.
    Max Weber (1864–1920)

    A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.
    Norman Mailer (b. 1923)
