This states that mass flow rate exiting a pipe is force.
Velocity is no longer needed to calculate force.
Obviously flow rate by itself is not force.
Is he/she saying that you might as well pour the rocket fuel directly out of the exhaust pipes without igniting it to create thrust because the mass is all that matters???
"Stupidity renders itself invisible by assuming very large proportions. Completely unreasonable claims are irrefutable. Ni-en-leh pointed out that a philosopher might get into trouble by claiming that two times two makes five, but he does not risk much by claiming that two times two makes shoe polish." B. Brecht
