Question

water flows into a tank at rate of 2.5 litre per second calculate the time taken to fill a tank with a rectangular bass 75 cm by 100 cm to a height of 64 metre​

Answer 1

Answer:

Length of tank = 75 cm

Breadth of tank = 100 cm

Height of tank = 64 cm

Volume of tank = Length \times Breadth \times HeightLength×Breadth×Height

Volume of tank = 75 \times 100 \times 6475×100×64

Volume of tank = 480000 cm^3480000cm

1 cm^3 =0.001 l1cm

3

=0.001l

So, 480000 cm^3 =0.001 \times 480000480000cm

3

=0.001×480000

480000 cm^3 =480 l480000cm

3

=480l

2.5 liters of water flows in tank in seconds = 1

So, 1 liter of water flows in tank in seconds =\frac{1}{2.5}

2.5

1

So,480 liter of water flows in tank in seconds =\frac{1}{2.5} \times 480

2.5

1

×480

So,480 liter of water flows in tank in seconds =192192

Hence it will take 192 seconds to fill the tank.
