Question

500 persons to define a rectangular tank with 80 metre long and 50 metre broad what is the rise in the level of water in the tank if the average displacement of water by a person is 4 m∧3 pls answer

Answer 1

Answer:

Volume of rectangular tank =l×b×h

=80×50×h=4000hm

3

(where 'h' is height of tank)

Average displacement of water by a person

=0.04m

3

∴ Average displace of water by 500 person =0.4×500=20m

3

Rise in water tank ⇒4000h=20

⇒h=

200

1

⇒h=.005m

⇒h=.005×100cm=0.5cm

Hope it helps✌
