A typical car has 17 I of liquid coolant circulating at a temperature of 93 °C through the engine's cooling system. Assume that, in this normal condition, the
coolant completely fills the 3.5 I volume of the alluminum radiator and the 13.5 I internal cavities within the steel engine. When a car overheats, the radiator,
engine and coolant expand and a small reservoir connected to the radiator catches any resultant coolant overflow.
Estimate how much coolant overflows to the reservoir if the system is heated from 93 °C to 105 °C. Model the radiator and engine as hollow shells of
aluminum and steel, respectively. The coefficient of volume expansion for coolant is 3 = 410 · 10–6 /C°.
Incorrect
AV =
78.5
Your Answer:
78.5
Correct Answer: 74.82 + 2.0%
