The agenda hot problem: Large thin metal sheet of length L are dipped in an electroplating bath in the vertical position. How rapidly will they come to the bath temperature? Make assumption and develop (a) a conceptual and (b) the numerical solution supported with the appropriate graph of Tpuen=f (time). Input data: L=2m, thickness =4mm,Tin=20C,Tbuih=80C, metal (plain carbon steel) properties): pnt=7854kgm3,kn=60.5Wm1K1,cpn=447Jkg1K1
