Consider laminar flow of a fluid with 3u 4 that undergoes a combined entrance process within a constant surface temperature tube of length / [fdw with a flow rate of . an engineer suggests that the total heat transfer rate can be improved if the tube is divided into 1 shorter tubes, each of length /1 //1 with a flow rate of . determine an expression for the ratio of the heat transfer coefficient averaged over the 1 tubes, each experiencing a combined entrance process, to the heat transfer coefficient averaged over the single tube, .

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
