Which outcome arises when estimating pressure drop through a venturi meter using Bernoulli's equation without accounting for a high Reynolds number?

💡 Explanation

An underestimated pressure drop occurs downstream because viscous effects and turbulence increase energy dissipation; thus, the simplified Bernoulli equation, assuming inviscid flow, fails; therefore, pressure drop is underestimated rather than accurately/overestimated, because viscous damping diminishes total mechanical energy.
