Question details

1. An insulation layer is added to a pipe to reduce heat loss from the pipe, as shown in the nsulation layer is r2. The figure. The outer radius of the pipe is r and the outer radius of the i thermal conductivity of the insulation material is k. The surface temperature of the pipe is fixed at T and the convection heat transfer coefficient is fixed at h, with or without the insulation layer. The ambient temperature is Too (Too < Ti). Suppose the pipe radius r is less than k/h. Perform analysis to find a relation equation that can be used to determine the minimum insulation outer radius r2 min such that the added insulation layer will not enhance heat loss. The relation equation should only contain ri, rcr.cylinder, and r2.min Insulation k 2 71
