Answer:
t = 2.26 10⁵ s
Explanation:
Let's calculate the flow of water that comes out of the hose
Q = A v
The area of a circle is
A = π r²
Q = π r² v
Let's reduce the units to the SI system
d = 5/8 in (2.54 10⁻² m / in) = 1.5875 10⁻² m
r = d / 2 = 0.79375 10⁻² m
Q = π (0.79375 10⁻²)² 0.59
Q = 1.1678 10⁻⁴ m³ / s
Let's calculate the volume of the pool
V = π R² h
V = π (4.6 / 2)² 1.6
V = 26.59 m³
Let's use a rule of proportions (rule of three), to find the time
t = 26.59 (1 / 1.1678 10⁻⁴)
t = 22.77 10⁴ s
t = 2.26 10⁵ s
