Answer #1

Bernoulli’s Equation is a equation that shows conservation of energy when a fluid is in motion.

So density is always present in Bernoulli’s Equation..

within a horizontal water pipe that changes diameter, regions where the water is moving fast will be under less pressure than regions where the water is moving slow.

So, both pressures and velocity is also again present, only 'gravity' is absent.
