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 greater viscosity (thicker, like honey) will flow more slowly, so as viscosity increases, flow rate decreases. The first option is wrong (greater viscosity should slow flow). The second is wrong (faster flow rate means lower viscosity, not greater). 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 options are labeled A - D in order, with the last option being D)
