SUMMARY
The discussion centers on the application of Bernoulli's equation and momentum principles in fluid dynamics, specifically regarding the treatment of gauge pressure versus atmospheric pressure. It is established that atmospheric pressure is typically omitted in calculations because it cancels out when both pressures are atmospheric. However, when one pressure is atmospheric and the other is not, the atmospheric pressure is still disregarded, leading to confusion. The consensus is that this omission simplifies calculations without affecting the outcome, as long as the same reference point is used consistently.
