A 60.00 L fuel tank is filled with gasoline on a –10°Cday, then rolled into a storage shed where the temperature is 20°C. If the tank is not vented, what minimum volume needs to be left empty at filling time so that the tank doesn’t rupture as it warms?

Short Answer

Expert verified

The minimum volume of 1.7 L. needs to be left empty at filling time so that the tank doesn’t rupture as it warms.

Step by step solution

01

Description 

A 60.00 L fuel tank is filled with gasoline on a – 10°day, then rolled into a storage shed where the temperature is 20°C.

The process of thermal expansion occurs when objects are heated as well as expanded. In case the temperature of an object changes through T, as well as volume changes through Vand the volume's fractional changes V/Vare effective to the temperature's change T.

02

Result of finding the minimum volume 

The equation (18.9) in the form is

VV=βT(1)

In this case, βis the coefficient. Table 18.4 effectively gives the coefficient expression of linear for common materials, for instance

gasolineβ=9.6×10-4C-1

Equation (1) for V=βVT

In this case, V is the initial volume. The temperature effectively changes from T1=-10°CtoT2=20°C

Therefore, the change in temperature is

role="math" localid="1649072092192" T=T2-T1=20°C-(10°C)=-30°C

Thus, plug the values of β,V,Tinto equation (2)

V=βLT=(9.6×10-4°C-1)(60L)(30°C)=1.7L

Therefore, the minimum volume of 1.7 L. needs to be left empty at filling time so that the tank doesn’t rupture as it warms.
