Question

water is flowing at the rate of 10km/hr through a pipe of diameter 16cm into a cuboidal tank of dimension 22m x 20m x 16m . how long it will take to fill empty tank ?

Answer 2

Step-by-step explanation:

rate of water flow = 10 km\hr

=1000000 cm\hr

diameter = 16 cm

radius = 16\2=8

volume of cuboid = l×b×h

l=22 m=2200 cm

b=20 m=2000 cm

h=16 m=1600 cm

let the time taken be t

= 1000000 × t × $\pi r^{2}$  = l×b×h

=1000000 × t ×$\frac{22}{7}$×8×8 =2200×2000×1600

=t =2200×2000×1600×7÷ 1000000×22×8= 35

therefore the total time taken to fill the tank is 35hr
