Apparatus for discovering underwater forces

C15-5534-W0

【Product Description】

All-in-one type apparatus for experiments of water pressure and buoyant force

【Overall Advantages to Users】

  • Set of equipment required for students’ experiments in groups to determine water pressure and to measure buoyant force, including [1] “Water Pressure Indicator” (C15-5530-W0), [2] “Square Prism Water Tank” (C15-5550), [3] “Cubic specimens set for measuring buoyant force” (C15-5351) and [4] “Newton spring balance SO-2N” (A05-4053-01). Features of [1], [2] and [3] are as follows:
    • [1] Easy to observe visualized water pressure by checking how the degree of dent in the thin rubber film changes depending on the water pressure exerted at the water depth where the indicator is.
    • [2] Versatile acrylic tank for various types of water pressure experiments in combination with “Water Pressure Indicator”, thanks to its vertically long shape for sufficient water depth.
    • [3] Possible to measure the buoyant force of each cube by comparing the gravity forces in newton unit acting on the cube in the air and underwater respectively. Designed to understand Archimedes’ principle by measuring buoyant forces acting on cubes that differ in substance, weight, and volume.
      Set includes in total six cubes. Two cubes each made of aluminum, polyvinyl chloride (PVC), and wood with different volumes.

【To all users】

  • The “Water Pressure Indicator” is named after its drum-shaped indicator designed to rotate longitudinally with two high-sensitive thin films. Hence, easy to observe visualized water pressure by checking how the degree of dent in each film differs between the upper (shallower) one and the lower (deeper) one.

【To teachers】

  • Shorter experiment preparation time required thanks to the all-in-one set for students’ experiments in groups.

【To students】

  • Easy to understand the concept of water pressure including how it differs depending on the water depth once it is visualized by the “Water Pressure Indicator”.
  • Easy to understand Archimedes’ principle through comparative experiment of buoyant forces acting on two cubes of:
    1)the same substance and same volume,
    2)the same substance and different volume,
    3)different substances and the same volume, or
    4)different substances and different volumes.
