    Heat transfer flow relationship

    Thanks for your help. Please can you point me in the right direction, Terminus, you mention multiple equations, can you tell me what they are.. IRStuff, you say this is for a thermal engineer, at the moment Im the best we have got ! Where do i start looking that (s)he would look? Rheology...

    Heat transfer flow relationship

    Hi, Im hoping someone can help me out, Id like to understand the rules around flow in a heat exchanger and how they link to heat transfer. I have a CHP engine generating electricity and heat is recovered from a water cooling system on board through plate heat exchanger where it heat process...

    Pump Flow and Exchanger Potential

    Hi I wrote recently with a heat exchanger fouling issue that people helped me with. I understand the fundamental rules: Q = UA LMTD and Q = m x Cp x dT but someone pointed out to me that fouling will cause the time element to change by reducing pump flows. I have two questions relating to...

    Heat Ex Fouling

    Thanks for all your replies, racookpe1978 perhaps you can help me out some more with a few questions relating to pump flow If I have a pipe transferring from a boiler to a heat exchanger. The pipe is 100meters long, the water at the beginning of the 100m is at 90C exactly. At the end of the...

    Heat Ex Fouling

    Hi I have a problem with a fouling heat exchanger. The fouling has happened over the last 3 months. Please can you confirm my assumption that the more fouled the heat exchanger the hotter the temperature of the hot water will need to be to transfer into the product? In the diagram the three...
