Question

Q 17. At a particular instant, water comes out of a valve at the bottom of a tank with a
speed of 20 ft/s. The height of water in the tank is
A) 20 ft
B) 12.5 ft
C) 6.25 ft
D) 25 ft​

Answer 1

Answer:

Height of water in Tank = 6.25 ft

Explanation:

At a particular instant, water comes out of a valve at the bottom of a tank with a

speed of 20 ft/s. The height of water in the tank is

A) 20 ft

B) 12.5 ft

C) 6.25 ft

D) 25 ft​

V² - U² = 2aS

V = 20 ft/s

U = 0

a = g = 9.8 m/s  = 9.8 * 100/30.48 ft/s = 32.15 ft/s

S = height of water in tank

20² - 0 = 2(32.15)S

=> S = 6.22 ft

Height of water in Tank = 6.25 ft
