Question 7 WAEC_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • essay

A cylindrical tank of height 12.0 m and radius 3.0 m is open at the top and filled with water. A small hole of negligible area is opened at a point P located 4.0 m below the water surface. Water streams out horizontally from the hole and lands on the ground at a horizontal distance d from the base of the tank.

Question Parts

( a )

Determine the speed of water as it exits the hole using Torricelli’s theorem.

( b )

Calculate the horizontal distance d the water jet travels before striking the ground.

( c )

If the tank were filled with oil of density 800 kg·m⁻³ and the same hole is at the same depth, what would be the new horizontal distance? State any assumptions you make.

( d )

Discuss two practical reasons why the actual distance measured in an experiment might be less than the theoretical value obtained in part (b).
