Get PriceDec 13, 2020 Explanation. The critical radius of insulation. The critical radius of insulation can be defined in many ways. Lets see them all together. The value of R outer for which the heat transfer rate is maximum is called the critical radius of insulation. The thickness up to which heat flow increases and after which heat flow decreases is termed as c ritical thickness. Apr 18, 2018 There are many variables (perhaps as many as 20) which affect good head design, such as the conical angle, trunnion length critical thickness, and critical radius just to mention a few. A field-proven computer program has made possible the performance of multiple calculations to permit analysis of effects of changes in head geometry on critical ...
