Qi and the carryover Q2 flows so that Tu = 7\. It is further assumed that there is no energy generation and negligible heat transfer. Hence, for the unloaded portion of the film, QiTt + Q2^T2 = (Q2 + Q1)(T1) Next an energy balance is performed on the active portion of the lubricating film (Fig. 28.6). The energy generation rate is taken to be Fj UIJ, and the conduction heat loss to the shaft and bearing are taken to be a portion of the heat generation rate, or XFj UIJ. Accordingly, PGiCT1 - (?QsaC*Ta + PQ2CT2) + fl"^*7 =O (28.13)...
