Coolant reservoir Radiato 4.1 x 10 The radiator is made of copper, and the coolant has a coefficient of volume expansion of C. If the radiator is filled to its 15 quart capacity (1 quart 0.000946 3) when the engine is 51 x 10 cold (6 C), how much overflow from the radiator will spill into the reservoir when the coolant reaches its operating temperature of 92 c?

beta = 4.1 x 10^-4 ; V = 15 quart ; Tc = 6 C ; Th = 92 C
beta(Cu) = 51 x 10^-6
We know that with the increase of temperature both the coolant and the reservior will expand. the liquid that overflow cab be caluclated using the diffrence in volume.
when the temp is T = 92 - 6 = 86 deg, the coolant expands :
delta V = beta V0 detaT = 4.1 x 10^-4 x 15 x 86 = 0.53 quart
when the temp is T = 92 - 6 = 86 deg, the radiator expands :
delta V = beta V0 detaT = 51 x 10^-6 x 15 x 86 = 0.066 quart
overlow: V = 0.53 - 0.066 = 0.45 quarts
Hence, V = 0.45 quarts = 4.25 x 10^-4 m^3
