    Heat Loss

    Kuhjo, I recently just prepared a spreadsheet to do just that (Determine heat loss from an Asphalt Storage Tank). I had to go back to the basics of Heat Transfer: Flow around a cylinder, flow over a flat plate, heat loss to ground, natural convection inside the tank, conduction, etc. You may...

    Pipe Supports - Material Issue

    In order for galvanic corrosion to occur, three elements are required. 1) Dissimilar metals 2) Metal-to-metal contact 3) Metals in the same conduction solution (usually called an electrolyte) If any of these elements is missing, galvanic corrosion cannot occur. So if there is no chance of an...

    Pump sizing question - several pump inlets w/ common header

    I would suggest you determine the NPSHa (Net Positive Suction Head Aviavble) with all three pumps running and compare to the NPSHr (Net Positive Suction Head Required) for each individual pump. As for a good book, I'm not sure off hand, but I think a quick “Google” of NPSH will give you most of...

    Pipe Supports - Material Issue

    I have a similar situation and I suspect I will go with solution No. 3 as well. But I though I would share the following: 304SS is considered a cathode (noble metal) Carbon/Gal Steel is considered an anode (active metal) The relative area of each of the exposed metal surfaces is also a...
