Water is circulating through a closed system of pipes in a two floor apartment. On the first floor, the water has a gauge pressure of 3.30 105 Pa and a speed of 2.0 m/s. However, on the second floor, which is 4.4 m higher, the speed of the water is 3.5 m/s. The speeds are different because the pipe diameters are different. What is the gauge pressure of the water on the second floor

P₂ = 2.82755 * 10⁵ Pa

Explanation:

Parameters for the first floor:

Guage pressure, P₁ = 3.30 * 10⁵ Pa

Speed, v₁ = 2.0 m/s

Height of the first floor = h₁

Parameters of the second floor:

Guage Pressure, P₂ = ?

Speed = 3.5 m/s

height of the second floor = h₂

From the question, h₂ - h₁ = 4.4 m, i.e. h₁ - h₂ = - 4.4 m

Density of water,

According to the Bernoulli's equation

what type of charge does it have? negative
