Question

A child holds a garden hose so that the outlet is parallel to the ground causing the water to flow vertically straight up out of the hose, and he observes the water to rise to a maximum height of h1 = 20 cm above the outlet of the hose. The child then places his thumb over the outlet of the hose so that 2/3 of the outlet area is covered by his thumb. Determine the maximum height that the water will now flow vertically upward out of the hose. Hint: Recall that for free fall, the equation v2 = v2 0 2g(y y0) is valid

Explanation / Answer

Velocity of water will be 3 times

maximum height will be 9 times

H= 0.2*9 = 1.8 meter
