1. Which of these statements is a correct expression of Fourier's Law a)q=mC, AT; b)qx = dT -k dx T -; c) qx - k- ; d) Q =-k- k; e) Q -; e) Q =-k- Ox 2. Which is the correct form of the 2D steady state conduction equation for constant thermal a)- T 4) T T 18 b) T T=0;c)+ x 3. Conductivity, in Cartesian coordinates? = 0; Which of the following is NOT a boundary condition? . Tx=L = 50C qx=L = qinput -k(dT/dx)x L = h(Ts - Tf) Ty=L/2 TO(1 - x/L) = k = 16 W/m K 4. The statement Tx=0 = T0, means that: the temperature at x = 0 is zero the temperature at x = 0 is constant the temperature at x = L is zero the temperature at x = L is constant the surface at x = 0 is adiabatic 5. The statement -k(dT/dx)x=L = h(Ts - Tf) means that: the temperature at x = L is constant the heat flux at x = L is constant heat transfer by convection is zero at x = L . heat transfer by conduction is zero at x = L . heat transfer by convection equals that by conduction at x = L
