Athin stream of water flows smoothly from a faucet and falls straight down. at one point the water is flowing at a speed of v1 = 1.23 m/s. at a lower point, the diameter of the stream has decreased by a factor of 0.787. what is the vertical distance h between these two points?

The vertical distance between these two points is 12.28 cm.

Explanation:

Given that,

Speed of water = 1.23 m/s

Diameter at lower point d'= 0.787 d

We need to calculate the speed of water

Using continuity equation

Put the value into the formula

We need to calculate the  vertical distance h between these two points

Using Bernoulli theorem

Here, P₁ = P₂ = atmosphere pressure is same because both end is open

Hence, The vertical distance between these two points is 12.28 cm.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
