# Water tank

The water tank has a cylindrical shape with a base diameter of 4.2 m and is 80 cm deep. How many minutes will take fill it 10 cm below the edge of the tank if water flowing 2 liters per second?

Result

t =  80.817 min

#### Solution:

$D = 42 \ dm \ \\ h = (80-10)/10 = 7 \ dm \ \\ r = D/2 = 42/2 = 21 \ dm \ \\ V = \pi \cdot \ r^2 \cdot \ h = 3.1416 \cdot \ 21^2 \cdot \ 7 \doteq 9698.0965 \ dm^3 \ \\ v = 2 \cdot \ 60 = 120 \ l/min \ \\ t = V/v = 9698.0965/120 \doteq 80.8175 = 80.817 \ \text{ min }$
