●Willan’s line method (also known as
the fuel rate extra-polation method) is used to calculate frictional power.
●In this method, we draw a graph where we take brake power on x-axis and fuel flow rate on y-axis on a condition that the engine is running at a constant speed.
Hence, the correct option is (D).
&Key Points:-
●Willan’s line method is only used in
the Compression Ignition (CI) engines. It is notapplicable to SI engines.
●Thefrictional power given by this
method is approximated.
