Question

time required to fill water in a tank of size 4×3×8meter with a pump whose capacity is 240liters per min?​

Answer 1

volume of tank = lbh = 4×3×8 = 96 m^3

we know that 1 m^3 = 1000 litre

so 96 m^3 = 96000litres

rate of pump = 240 litres = 1min

1 litres = 1/ 240

96000 litres = 1/240 × 96000

= 400 min = 6hrs 40 min...
