Question
a large storage tank open to the atmosphere at the top and filled with water develops a small hole in its side at a point 16 m below the water level. the hold is 5m above ground find where the water hits the ground.A. Find the speed of the water as it leaves the hole. B. Find where the water hits the ground a large storage tank open to the atmosphere at the top and filled with water develops a small hole in its side at a point 16 m below the water level. the hold is 5m above ground find where the water hits the ground.
A. Find the speed of the water as it leaves the hole. B. Find where the water hits the ground a large storage tank open to the atmosphere at the top and filled with water develops a small hole in its side at a point 16 m below the water level. the hold is 5m above ground find where the water hits the ground.
A. Find the speed of the water as it leaves the hole. B. Find where the water hits the ground
A. Find the speed of the water as it leaves the hole. B. Find where the water hits the ground
Explanation / Answer
a) the speed at which the water leaves the hole
Velocity of flow = (2gh)^0.5 (same as velocity of an object dropped from height h)
V = (2*9.8*16)^0.5 = 17.7 m/s
b) time required to reach ground is
t = (2*h/g)^0.5 = (2*5/9.81)^0.5 = 1.0096 sec
horizontal distance is
x = 17.7*1.0096 sec = 17.869 m
