i dnt have any clue of d operating pressures. initially i knew only required flow rate and tube dimensions that gave me the pressure difference reqd.

Greetings, I need to know which gas/liquid can absorb high amount of heat when passed through a hollow copper tube, heat is generated on the tube. The gas/liquid should not be conducting at ant point. If possible the conductor should absorb more heat than is generated at the tube.i.e...

1.67 kJ/kg.K

id=6.5mm,od=8.2mm,,,,,,,,id=4.9mm,od=5.5mm

hey sry,,,inlet is 25,,,n outlet is 80c

I know the needed pressure difference, and that is 3.92 bar,velocity of flow being 0.7m/s.its electrolytic copper(99.9%pure).ASTM spec...inlet temp 80c and outlet 25c

hey thanks matt!well i don't have access to that, could you please help me with that

I am using mineral oil..the one used in transformers..i need to find out the stress at every point.

Hey Matt, very rough sketch though,but will give you an idea of the system, the two coils are separated by some kind of insulation.

k..i wil sketch a rough figure.

Thanks Matt! Well these are coils(round, similar to a suspension used in automobiles) one overlapping the other, I am through with the temp calculations but for presenting it to my boss I need to have a model which is simulated and shows the heat at tube at different points and...

hello all, i am from electrical background and for a project i need to analyse the flow of oil through a hollow copper tube when the tube is subjected to some amount of heat. the outcome should tell me if the heat will be absorbed by the oil and what would be the stress points when i apply...

dont you think Hazen-Williams formula would be a better option

so increasing diameter is the only solution?

hey i tuk length(ft)=25721.78...flow rate=.6023332gpm,,,,and with a new diameter of 17.78mm=.7inch...we get pressure drop=28psi...flow rate was calculated from Q=mC(T2-T1)...temp change was assumed from 100-25...12kW heat was to be absorbed...from that calculate flow rate,,correct me if i am...
