Water is pouring into a cubiodal reservoir at the rate of 2.5 litres per second. If thedimension of the reservoir are 75cm×100cm×64cm. Calculate the time taken to fill thereservoir(in seconds).

Answer»

Rate of flow of water = 2.5 litres/second

Volume of the tank =480000 cm³=0.48m³

1 m³ = 1000 litres

0.48m³ = 480 litres

Time taken to fill the complete tank = 480/2.5

= 192 seconds

Hence,The tank will be filled completely in 192 seconds
