I need to evaluate heat loss in an uninsulated underground (1 m) tank (20 m3) due to freezing problems.
I have some values for apparent thermal conductivity for different soils based on soil type and moisture content, but I don't know how to estimate the equivalent thickness to calculate the...
I have a tank bottom's spiral jacket and I need to estimate the pressure drop for water flow.
I looked in Perry's:
"the pressure drop for flow in spirals es discussed by Srinivasan...." but there is no formula and I'm not able to found it in any article.
Could anyone help me?
thanks in...
