Three sets of parallel plates LM, NR and PQ are given in Figures 1,2 and 3 . The view factor ${\mathit{F}}_{\mathit{u}}$ is defined as the fraction of radiation leaving plate I that is intercepted by plate $\mathit{J}$. Assume that the values of ${\mathit{F}}_{\mathit{L}\mathit{M}}$ and ${\mathit{F}}_{\mathit{N}\mathit{R}}$ are $0.8$ and $0.4$, respectively. The value of ${\mathit{F}}_{\mathit{P}\mathit{Q}}$ (round off to one decimal place) isThree sets of parallel plates LM, NR and PQ are given in Figures 1,2 and 3 .
