A block of metal at T1o C is placed in an environment at T2o C. The rate of heat transfer from the metal to the environment is given by W = k1(T1-T2). The metal has specific heat k2 J/degree. Find an equation for the temperature of the metal.
A flow system has a model equivalent to two parallel resistances: one path has resistance R1=1 and the other path has an element of resistance 1 and two more series elements of resistance: (i) R2 which is the greater of 0 and cos(2 - /4) and (ii) R3 which is the greater of 0 and sin(2 - /4) respectively.
Find all the values of such that the overall resistance is a maximum (i.e. derivative is zero).
Plot a MATLAB graph showing how the overall resistance varies with to validate your answer.
