Question

which of the following best describes the relationship between viscosity and flow rate? the greater the viscosity, the faster the flow rate. the faster the flow rate, the greater the viscosity. viscosity and flow rate are unrelated. the greater the viscosity, the slower the flow rate.

Explanation:

Viscosity is a measure of a fluid's resistance to flow. A fluid with higher viscosity (thicker, like honey) will flow more slowly, so as viscosity increases, flow rate decreases. The first option is wrong (higher viscosity slows flow). The second is wrong (faster flow doesn't mean higher viscosity; e.g., water flows fast and has low viscosity). The third is wrong as they are related. The fourth correctly states the inverse relationship.

Answer:

D. The greater the viscosity, the slower the flow rate. (Assuming the last option is D; if options are labeled differently, adjust the identifier, but the text is "The greater the viscosity, the slower the flow rate.")
