बर्नौली के सिद्धांत के अनुसार, जब किसी संकुचन (constriction) से गुजरने वाले एक असंपीड़ित (incompressible) तरल का वेग बढ़ता है, तो उसके दबाव पर क्या प्रभाव पड़ता है?

The product of the cross-sectional area of flow in the river and the average velocity of flow is known as _________.

As compared to a laminar flow, the boundary layer thickness in a turbulent flow is:

A body is fully submerged in a surrounding fluid. If the flow speed corresponds to a ratio U√(E / ρ) ≤ 0.3 (incompressible flow) and change in density is insignificant, which forces/numbers can be neglected in dimensional analysis to derive drag and lift coefficients?
