1.	What is the significance of second fuel flow law?(a) specific fuel consumption is not considered(b) considers temperature and effects of mach number(c) assumptions are taken for empirical fuel flow data(d) specific fuel consumption is constantThe question was asked by my college professor while I was bunking the class.This intriguing question comes from Range and Endurance for Aircraft with Thrust Producing Engines topic in chapter Cruising Performance of Aircraft Performance
Answer» Right OPTION is (b) considers temperature and effects of mach number The explanation: The significance of first fuel flow LAW is that the specific fuel consumption is constant. The significance of second fuel flow law is that it considers temperature and effects of mach number. The significance of third fuel flow law is that assumptions are TAKEN for empirical fuel flow DATA.
