Explain how the \(f\)-chart (Figure 7.32) can be used graphically to determine the solar load fraction for a range of collector sizes once the solar and loss parameters have been evaluated for only one system size. Consider a straight line passing through the origin and the point \(\left(P_{s}, P_{L}\right)\).
