Final answer:
To find the total outward force on the window, we calculate the area of the window (55 inches by 60 inches) to get 3300 square inches, then multiply this by the pressure (6 psi), resulting in a total outward force of 19800 pounds-force.
Step-by-step explanation:
The question asks about the total outward force exerted on a viewing window of specific dimensions by water at a certain pressure within a large tank. The formula to calculate this force is the product of the pressure exerted by the water and the area of the window. In this case, the pressure is given as 6 psi, and the area can be calculated by multiplying the length and width of the window.
First, let's convert the dimensions of the window to square inches to match the pressure units (psi):
- Width: 55 inches
- Height: 60 inches
To find the area, we multiply the width by the height:
Area = Width × Height = 55 in × 60 in = 3300 in²
Now, we can calculate the force using the formula:
Force = Pressure × Area = 6 psi × 3300 in²
Force = 19800 pounds-force
Therefore, the total outward force on the window is 19800 pounds-force.
