Unit Conversions A solution (? = 1.03 g/mL) that is a mixture of water and 5wt% sufuric acid (H2SO4) ?ows through a 45-m long pipe with a 6.0 cm diameter at a rate of 87 L/min.
a. What is the molarity (mol/L) of sulfuric acid in the solution?
b. How long (in seconds) would it take to ?ll a 55-gallon drum, and how much sulfuric acid (lbm) would the drum contain?
c. The average velocity of a uid in a pipe equals the volumetric ?ow rate divided by the cross-sectional area normal to the direction of tow. Use this information to estimate how long (in seconds) it takes the solution to ?ow from the pipe inlet to the outlet
