Question

Solve the problem with complete and proper solutions. What height of gasoline column will enter a pressure of 32.1 torr? Assuming that the density of gasoline is 1.68 x 10^3 kg/m^3.

Answer 1

1) Convert 32.1 torr to Pa: 4279.6 Pa.

2) Write the equation for pressure:

$$p=\rho gh→h=\dfrac{p}{\rho g},\\\space\\ h=\dfrac p{\rho g}=0.26\text{ m},$$

or 26 cm.
