Problem 1 hen a thick flat plate, initially at a uniform temperature is suddenly immersed in a huge bath the temperature distribution is given by the dimensionless temperature ratio 4 sin( n) Tratio = 'sin (2%)+26/ cos(8nx) exp(-6ft) n where : the dimensionless horizontal distance from the center of the slab : Fourier number (dimensionless time) Bi: the Biot number (dimensionless heat transfer coefficient) : given by -(n-1/2 ) T Initially T 0 2L Figure 1: A slab undergoing unsteady heat transfer Using "subplot(m,n,p)" command to plot the following figures (one above the other in the same figure window) a. b, c. Plot Tratio vs. for 0 1, -0.1 (hint: use nested looping or vectorize) Plot Tratio vs. for 0 0.2, -0.6 (hint: use nested looping or vectorize) Is the plot consistent with those of unsteady heat conduction in a slab?
