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:
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
“Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.”
—Cyril Connolly (1903–1974)
“The Soul rules over matter. Matter may pass away like a mote in the sunbeam, may be absorbed into the immensity of God, as a mist is absorbed into the heat of the Sun—but the soul is the kingdom of God, the abode of love, of truth, of virtue.”
—Ralph Waldo Emerson (1803–1882)
“If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.”
—Jackie Torrence (b. 1944)
“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)
