Web2 . We use a shell balance approach. Consider a cylindrical shell of inner radius . r and outer radius rr+∆ located within the pipe wall as shown in the sketch.The shell extends the entire length L of the pipe. Let Qr( ) be the radial heat flow rate at the radial location r within the pipe wall. Then, in the end view shown above, the heat flow rate into the cylindrical … WebAs noted, a Biot number smaller than about 0.1 shows that the conduction resistance inside a body is much smaller than heat convection at the surface, so that temperature …

Webcylindrical geometry, a number of guess temperature profiles have been assumed to obtain a generalized solution. Based on the analysis, a modified Biot number has been proposed that predicts the temperature variation irrespective the geometry of the problem. In all the cases, a closed form solution is obtained between temperature, Biot number,
