I understand the practical answer and the additional heat loss concepts.
My question aims at how the nature of turbulence affects the freezing point. From my observations, it is much harder to freeze turbulent water (fast moving streams in sub zero temps, ocean water, etc)
Couldn't the concept...
How fast do i need to pump water in a 10" aluminum pipe to prevent freezing? Assume 32*F inlet temp and 0*F ambient . For my conditions, the temps will vary and T ambient easily gets down to -20*F or more.
Boyle's Law applies here: p1v1=p2v2
I am assuming barometric pressure is p1
p2 is calculated by hydrostatic pressure
p2=p1+density*g*height
v1 = pi*r2*h1 (convert units)
v2= p1v1/p2
h2=v1/(pi*r2)
I get 5.2 cm
