Question

A rectangular tank is 9m by 4m water
flows into it throught a pipe whose cross
section is 5cmx3cm at the rate of10m/s. In who much time will water
be 1m, deep.​

Answer 1

Answer:

Let 't's taken by a pipe to fill the tan

Cuboidal Tank:

l×b×h = 9 × 4 × 1 cubic m

volume of water flow through a cuboidal pipe in t seconds = 5/100 × 3/100 ×10

t =

$\frac{9 \times 4 \times 1 \times 1000}{5 \times 3}$

t = 12 × 200 = 2400seconds = 40min
