Web23 nov. 2015 · 2. The well known Bernoulli's equation states that P + ρ V 2 2 = c. However, a simple momentum conservation considering P 1 and P 2 acting on two sides, and velocity changes from V 1 to V 2, yields P 1 + ρ 1 V 1 2 = P 2 + ρ 2 V 2 2, which differs from Bernoulli's by a coefficient 1 2. What is going on here? Web6 okt. 2024 · Embrace them, and always use them when needed. Also, you could come up with your own mnemonics. Say your name is Elaine. You could memorize the formula E = mc² with the mnemonic “Elaine loves meerkats and cats too.”. Here the “t” in too represents the power of 2 in the formula. You can also use a visual picture to store the formula.
