What is the depth of water in a tank with 300,000 gallons of water at 70F when the pressure gauge at the bottom of the tank read

chubhunter [2.5K]

Answer:

53.08 ft

Step-by-step explanation:

The pressure at the bottom of the tank, P = ρgh where ρ = density of water = 1000 kg/m³, g = acceleration due to gravity = 9.8 m/s² and h = depth of water in tank.

Since the pressure at the bottom of the tank, P = ρgh, making h subject of the formula, we have

h = P/ρg

Since P = 23 psig = 23 × 1 psig = 23 × 6894.76 Pa = 158579.48 Pa

Substituting the values of the other variables into h, we have

h = P/ρg

h = 158579.48 Pa/(1000 kg/m³ × 9.8 m/s²)

h = 158579.48 Pa/(9800 kg/m²s²)

h = 16.18 m

h = 16.18 × 1 m

h = 16.18 × 3.28 ft

h = 53.08 ft

The model represents an equation. What value of x makes the equation true?

goldfiish [28.3K]

Answer:

A. 2.25

Step-by-step explanation:

-3x + 10 = 5x - 8 (Given)

10 = 8x - 8 (Added 3x on both sides)

18 = 8x (Added 8 on both sides)

2.25 = x (Divided 8 on both sides)
