4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5
per minute.
Step-by-step explanation:
The given is,
Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
Oil drained at a rate of 2.5
per minute.
Step:1
Time taken to dry the oil tank is,
T =
....................................(1)
Step:2
Volume of the oil is,
.................................................(2)
Where, r - Radius of Cylinder
![r = \frac{2.2}{2}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B2.2%7D%7B2%7D)
r = 1.1 ft
From eqn (1),
V =
×
× 3
= 11.40398 ![ft^{3}](https://tex.z-dn.net/?f=ft%5E%7B3%7D)
Step:3
From equation (1)
=
= 4.56
= 4.56 minutes
T = 4 minutes 34 seconds
Result:
Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
