100 CHAPTER 5 1952 Guide Following the-electrical analogy, when there is a thermal current-flowing through several resistances in series, the resistances are additive: fiT = Ri + R + + -l" tt, (7) Similarly, conductance is the reciprocal of resistance, and for heat-flow through several resistances in parallel, the conductances are additive: 11 1 R--,--1-R---i-- 1-R-z---h (8) Practical Heat Transfer Problems ' The use of these relations for resistance and conductance makes pos sible the solution of many practical heat transfer problems.
