    Heat Transfer in a heat exchanger.

    I wanted to try and clarify this. If it is just a double tube simple heat exchanger like this shown here. http://i56.tinypic.com/34znmti.png *What is the calculation to calculate the heat transfer coefficient. *How much surface area would be required between the two pipes for the solution to...

    Heat Transfer in a heat exchanger.

    So this concept is confusing me. You have a 20GPM, 150Degree F, 40PSIG water coming into a heat exchanger through a 1" diameter pipe. Chilled water is available for cooling from a 6" diameter line at 40 Degrees F, With a pressure of 110PSIG and a flow of 270GPM. The original...

    Thin Film Processing Interfaces: Info & Resources

    I need to write up some stuff with general information about different interfaces used in Thin Film Processing. I'm pretty sure its a way to analyze the quality of the different procedures. * Abrupt Interface * Mechanical Interface * Graded Interface * Compound Interface * Psuedo...
