Question

water flows into a tank 150m long and 100m broad through a pipe whose cross section is 2dm by 1.5dm at the speed of 15 km per hour .in what time ,will the water be 3 M deep?

Answer 1

Answer:

100 hours

Step-by-step explanation:

Volume of water in the tank(V)

when depth is of 3 m

V = 150 × 100 × 3 = 45000 m³

Rate of volume of water flowing = 2 × 1.5 × 10^-2 × 15000 m³/hr = 450 m³/hr

so,

Time taken = 45000/450 hr = 100 hours
