THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Efflux speed
A draining jet also falls
Water exits horizontally from a small tank hole 0.80 m below the water surface and 1.25 m above level ground.
Find the horizontal distance travelled before hitting the ground.
Organize the givens & assumptions
- head = 0.80 m
- fall height = 1.25 m
g = 10 m/s²; large open tank, small horizontal hole, no drag or viscous loss; level ground below the hole.
