Thermodynamics - Heat Transfer vs. Velocity
2009-05-05 21:06:00 If I have a series of 8" diameter pipes 12 ft long that I'm running hot air through and I want to transfer heat through the pipes. What is the relationship between velocity & heat transfer? I know if I increase the velocity the heat transfer will increase but there must be a point where the velo
Heat Transfer
2009-05-02 17:03:00 I am presently trying to solve this problem at work. We have electric baseboard heaters (125 Watts/lin ft) in a hotel lobby with stainless steel grills that are approximately 10-12" above the floor. During operation of the heaters in winter the grills heat up to approximately 165 degrees F causing c

2008-08-28 05:20:00 hi, i have installed d/p flow transmitter on the steam line. i run leads from root valve to the transmitter about 6 meter, leads filled with demin water, i just want to know how much temperature will travel up to the transmitter? steam temp. 300 deg C
heat transfer rate of steam bubbling in a liquid
2008-08-25 11:58:00 <>How quickly does latent heat transfer from steam bubbles to a surrounding liquid? I've searched and can't find anything even remotely close to my question, and Fourier's Law (heat exchange formula) can't be used because we can't divide by zero (the thickness of the barrier when there is no ba
composition for low temperature heat transfer fluid
2008-08-24 10:17:00 I m intrested in to use low viscosity (about 15 cp at -40 deg C) and low temperature (-40 deg C)heat transfer fluid. Can any person give me the best chemical or mix for this requirement. SZafar
how can i design the coil for heat transfer
2008-07-21 03:49:00 we have one line of condensate (temperature-80-90c) which is contaminated so that we can not put directly to boiler feed tank water. its causing to increase tfm of boiler. but i want to transfer heat of condensate to boiler water by passing through coil. how can i design the coil of condensate to f
