Drop Ball Viscometer and Resistance Coefficient Determination Unit

The Drop Ball Viscometer and Resistance Coefficient Determination Unit, designer is used to determine dynamic or kinematic viscosities of fluids and the relationship between the drag coefficients of falling particles and their Reynolds number value.

ATENG 11771 — Drop Ball Viscometer and Resistance Coefficient Determination Unit

Anodized aluminum frame and panels made of painted steel.

Main metallic elements made of stainless steel.

• The “ATENG 11771” unit mainly consists of:
• Two transparent measuring cylinders:
• Internal diameter: 114 mm.
• External diameter: 120 mm.
• Length: 1.3 m.
  Both cylinders are marked longitudinally every 50 cm, so that the distance the ball travels
  after being thrown inside can be read.
• Two light sources placed between the tubes for ease of viewing. Power: 58 W.
  Two guides to aid the introduction of particles at the top of the tubes with the minimum
  disturbance to the liquid.
• Six couplings for the guides to make the introduction of smaller balls possible (5 mm, 10 mm

• and 15 mm).
  Two ball valves and two gate valves to aid the removal of balls from the bottom of the tubes, without a large loss of liquid.
• Sets of balls of different sizes:
• Ball 1 is made of stainless steel, diameter = 5 mm.
• Ball 2 is made of stainless steel, diameter = 10 mm.
• Ball 3 is made of stainless steel, diameter = 15 mm.
• Ball 4 is made of stainless steel, diameter = 20 mm.
• Ball 5 is made of stainless steel, diameter = 25 mm.
  Stopwatch.
• Two plastic beakers, capacity: 0.50 l each one.
  Cables and accessories, for normal operation.
