Cf. Giambattista/Richardson/Richardson, Physics, 2/e, Problem 1.25
The U.S. Environmental Protection Agency limits fuel dispensers[*] to a maximum rate of 10 gallons per minute. One gallon is equivalent to 3.78541178 liters. The maximum fuel dispensing rate in milliliters per second is:
(A) 0.16 mL/s.
(B) 6.3×102 mL/s.
(C) 2.3×104 mL/s.
(D) 2.3×106 mL/s.
[*] epa.gov/oms/regs/ld-hwy/evap/spitback.txt.
Correct answer (highlight to unhide): (B)
Converting 10 gal/min to mL/s:
10 gal/min × ((3.78541178 L)/(1 gal)) × ((1,000 mL)/(1 L)) × ((1 min)/(60 s)) = 630.90196333 mL/s,
or to two significant figures, 6.3×102 mL/s.
