Willian’s line follows the law (where b = A constant representing the shape of the Willian’s line, a = Another constant i.e. no load consumption per hour, I.P. = Indicated Power and m = Steam consumption per hour)
A. I.P. = a × m + b
B. m = a + b × I.P.
C. I.P. = b × m + a
D. $${\text{m}} = \frac{{\text{b}}}{{{\text{I}}{\text{.P}}.}} - {\text{a}}$$
