The ratio of brake power to indicated power is called -
Mechanical efficiency
Mechanical efficiency is a measure of how effectively the engine converts the internally developed power (Indicated Power) into usable power delivered at the output shaft (Brake Power). At higher loads (and thus higher IP and BP), mechanical efficiency tends to be higher because friction power is a relatively smaller fraction of the total power.
