Problem
A student compares how maple syrup and water drain from identical containers through identical nozzles at the same room temperature. The syrup drains much more slowly than the water. Which statement most reasonably accounts for the difference while considering the limitations of the ideal-fluid assumption?
(a) The ideal-fluid model assumes zero surface tension, and the higher surface tension of syrup opposes its flow, slowing drainage.
(b) The ideal-fluid model ignores viscosity, and the higher viscosity of syrup increases internal friction, reducing its flow rate.
(c) The ideal-fluid model ignores compressibility, and the smaller compressibility of syrup keeps it from accelerating rapidly through the nozzle.
(d) The ideal-fluid model assumes identical densities, and the greater density of syrup makes it harder to accelerate, so it drains more slowly.
