WebNow ,rearranging our flow rate equation in terms of volume, our calculations are as follows: Q = V t, V = Q t, V = ( 500 m 3 s) ( 3600 s), V = 1.8 × 10 6 m 3. Flow rate is also … Bernoulli developed his principle from observations on liquids, and Bernoulli's equation is valid for ideal fluids: those that are incompressible, irrotational, inviscid, and subjected to conservative forces. It is sometimes valid for the flow of gases: provided that there is no transfer of kinetic or potential energy from the gas flow to the compression or expansion of the gas. If both the gas pressure and volume change simultaneously, then work will be done on or by the gas. In this ca…
