    Siphon-Heat Exchange-Electric Generation

    Thanks for the previous inputs. I am in an information gathering mode. I am having trouble finding specs on radiator head loss. After tons of searching the best I could find was: Following is a typical Winston Cup engine at 100 GPM: Lower radiator hose = 1.5 PSI Block and cylinder head -...

    Siphon-Heat Exchange-Electric Generation

    So, I should not be trying to find the largest possible pipe dia. I should be trying to find the smallest possible pipe dia. to maintain my given flow rate and still not exceed the 30 ft head loss?

    Siphon-Heat Exchange-Electric Generation

    I am still trying to find the largest dia. pipe for a given flow rate. How big can I go with the worst case scenario of 0.35 gpm? There must be a calculation to come up with this answer. I understand all about starting a siphon but to maintain it, I need to keep the cross-sectional area...

    Siphon-Heat Exchange-Electric Generation

    In picturesque terminology; A 55 gallon barrel of water can only flow so fast through a pipe the size of a straw because of the resistance of the straw. It would flow faster if you just tipped the barrel over and let it flow through the 2 ft diameter open top, because there is less resistance...

    Yes, I did read it and responded. So I guess I do not understand it. Because: Is less than 30. It is 0.0 As I understand your statement the flow will not stop, however, I don't think there is enough water to fill the pipe. So, I am extremely thick in the skull. Please clarify. Thank you...

    Thanks for all the info In response to gmax137, Yes, I have consulted with our County’s water and soil dept. As long as I get permission from the 2 landowners below me I can dam the stream. It is irrelevant in my case, because I will not be interrupting the flow at all and any dam that I would...

    Siphon-Heat Exchange-Electric Generation

    This is how I understand it and please correct me where needed. Total length of pipe 1,050 ft, let’s just round off to 1,000 ft, (800 ft up and 200 ft down). If I go uphill 15 ft and then drop 45 ft, I have a gross head of 30 ft. According to...

    Siphon-Heat Exchange-Electric Generation

    If I understand you correctly, the 1250 ft of 2" pipe friction loss is equivalent to 30 ft head loss, which is the same as the total starting head of 30 ft, leaving me zero head at exit. When the loss is calculated in for screens, bends, radiator I will not be able to maintain the siphon as the...

    Siphon-Heat Exchange-Electric Generation

    Thank you for the response My main objective was a never ending flow of cool water, with no outside energy expended, that went through the greenhouse for cooling. Afterthought was, hmmm, I may even be able to get some electricity, however small, as a side benefit. If cavitation isn't an...

    Does anyone know if a siphon can be maintained with the information I have given?

    Siphon-Heat Exchange-Electric Generation

    Hi I haven't done the calculations. I was hoping to get some help from those of you that are well versed in hydraulics. I have limited the pipe dia to 2" as a good sized truck radiator inlet and outlet is 2" (at least I haven't found any larger yet) as well as the most economical flex pipe is...

    Siphon-Heat Exchange-Electric Generation

    Hello All I am new to this great forum. I would like some thoughts on my idea which is: I am designing a passive solar greenhouse for aquaponics. I am concerned about excess heat in the summer (I am in western NY Sate). A requirement is air exchange for a healthy interior environment. I am...
