Quiz 9 Q.1 & 2 & 10 see Table A-24 and A-25 (pgs 1023-1026) Q.3 See page 634 Q.4 see section 16-4 page 635 Q.5 see Eqn 16-9 on page 637 Q.6 the thermal conductivity of copper is around 400 W/m-K and soft rubber polymer is <1 W/m-K (see Table 16-1 pg 628) The resistance of the glue will almost always dominate Q.7 see pg. 655-656 Q.8 Contact thermal resistance is an issue any time two surface are pressed together Q.9 Heat has to be conducted through the boundary layer to be swept away. The boundary layer gets thinner as the velocity increases so the heat has to be conducted a shorter distance. Question 1 The thermal conductivity of window glass is roughly X 1 W/m-K 98.507% 20 W/m-K 0% 400 W/m-K 1.493% 2000 W/m-K 0% Question 2 The thermal conductivity of diamond is roughly 1 W/m-K 1.493% 20 W/m-K 0% 400 W/m-K 0% X 2000 W/m-K 98.507% Question 3 . In the equation Q = h A T the symbol h is enthalpy 5.97% height 0% X heat transfer coefficient 94.03% none of the above 0% Question 4 Radiation heat transfer depends on
