Technician A says that a diesel fuel tank plays a role as a heat exchanger in many modern diesel fuel systems. Technician B says that rectangular shaped fuel tanks can provide the same strength using thinner wall thickness than that required for cylindrical tanks. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because in many modern diesel fuel systems, the fuel tank does indeed act as a heat exchanger, helping to dissipate heat from the fuel as it circulates through the system. Technician B is incorrect because cylindrical tanks are inherently stronger and can withstand internal pressure with thinner walls compared to rectangular tanks, due to the even distribution of stress along the curved walls of the cylinder.
