Question

water is flowing at the rate of 2.5km/hr through a cylindrical pipe of radius 7cm into a reactangle tank of length 25m&25m width. in 5hrs how much water is arise in H² o tank

Answer 1

The value of width is not correct in the question. It must be 22m in width.

Answer 2

0.30m is the rise in the water level

Step-by-step explanation:

Rate of water flowing through the cylindrical pipe = 2.5 Km/hr

The Radius of the cylindrical pipe = 7cm 0r 0.07m

Length of water in 5 hours = 2.5 * 5 = 12.5Km 0r 12,500m

The total volume of the water filled in the tank(rectangular) = π$r^{2} h$

= π$(0.07)^{2}$ * 12,500

= $192.5m^{3}$

Assuming the rise in water level to be h,

Volume of water in the rectangular tank = L * B * h

so, 25 * 25 * h = 192.5

h = 0.30m
