Final answer:
The provided question regarding engine speed for the Kovatch-International R-11 Refueler is not related to the reference materials given, which discuss fluid mechanics and gasoline flow in pipelines. Hence, we cannot provide a specific answer to the question. The reference material includes calculations for pipe diameter and pressure difference based on flow rates, viscosity, and density of gasoline.
Step-by-step explanation:
The question pertains to determining the specifications for fluid flow within a pipeline system, specifically concerning gasoline transportation. To compute the minimum pipe diameter for a laminar flow (Reynolds number less than 2000), as well as the pressure difference required along a pipe to maintain a given flow rate, we can apply fluid mechanics principles that involve the Reynolds number, the Hagen-Poiseuille equation, and Bernoulli's equation. However, the initial question regarding the Kovatch-International R-11 Refueler engine speed for LOW FLOW servicing does not correlate with the reference information provided.
To find the minimum diameter, we need to use the Reynolds number formula: Re = (ρVD) / μ, where ρ is the density of gasoline, V is the flow velocity, D is the diameter, and μ is the viscosity. However, since neither the claim about car refueling at a gasoline station transferring energy nor the various rev/s options provided align with the required calculation, we cannot accurately answer this specific question.
