Question

Water is flowing at the rate of 15 km per hour through a pipe of diameter 14cm into a
rectangular tank which is 50 m long and 44 m wide. Find the time in which the level of
water in the tank will rise by 21 cm.

Answer 1

Answer:

Step-by-step explanation:

Volume of cylinder= vol.of cuboid

(X) πrsq×h=LBH. (X is time)

On solving .

H= 15000msq.

R=0.14/2

And

L=50

B=44

H for cuboid is 0.21msq.

On equating x=2minutes.

Answer 2

Heyy

⬇Here's ur answer

In cylinder,

r=7cm=0.7m

l=15km

 =15000m

In tank,

l=50m

b=44m

h=0.21m

Vol.of water in tank=lbh

                               =50*44*0.21

                               =462m³

Height of cylindrical pipe=Vol. / πr²

                                      =462/(0.07)²(22/7)

                                      =462/0.0154

                                      =30000m

Time = 30000/15000

         = 2 hours
