Question

Water is flowing at the rate of 10 km/hr through a pipe of diameter 14 cm into a
cuboidal pond which is 50 m long and 44m wide . In what time will the level of
water in pond rise by 21 cm.

Answer 1

Answer:

if the speed of water is 10km/hr the water will increase in the speed of .0784cm pre second

Step-by-step explanation:

i think it's the answer

Answer 2

Answer:

t=3hr

Step-by-step explanation:

10km/hr=> 10000m/hr

radius of pipe=14/2=>7cm => 7/100=> 0.07m

height of cuboidal tank=>21cm=> 21/100=>0

.21m

volume of cuboidal pond =50*44*0.21=>462m³

let the time in which pipe volume =volume of cuboidal pond be t.

h=10000m/hr*t=> 10000t

volume of pipe =22/7*0.07²*10000t=>154t m³

volume of pipe = volume of cuboidal pond

154t=462m³

t=462/154

t=3hr Answer
