Particle Drag Coefficients
The apparatus is designed to study the drag of a particle in a liquid under various Reynold numbers.
This is done by dropping a particle into a vertical liquid column and timing its fall between two points. Particle cross section is no more than 1% of the tube cross section. Various sizes and density of particles are supplied including stream lined shaped objects.
A guide at the top of the tube is provided to minimize disturbance to the liquid. Valves at the bottom of the tubes provide a mean for particle removal with minimum loss of the liquid. The rear panel is translucent with back lighting. This allows clear observation of the particle fall.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Measurement of drag coefficients of sphere under various Reynold numbers.
- Effect of particle shape on rate of fall and drag coefficient.
- Effect of boundary layer separation on motion of sphere.
- Exploration of dynamic similarity.
- Determination of viscosity.

Hydraulic Studies and AccessoriesPipe Friction
This equipment measures pressure drop when water flows through a vertical pipe at various flow rates both laminar and turbulent. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
It consists of adjustable constant head water source of removable clear acrylic cylinder for laminar flow. Turbulent flow may be achieved by directly connecting the pipe to the Hydraulics Bench water supply. A water manometer with a vent valve, a hand air pump and a differential pressure gauge are provided for measurement of pressure drop. A valve at the outlet is used to control outlet pressure.
TYPICAL EXPERIMENTS- Investigations of laminar and turbulent flows
- Demonstration and measurement in a change of the laws of resistance (friction factor) from laminar to turbulent flow

Hydraulic Studies and AccessoriesHydrostatics Pressure – Tilting Submerged Quadrant
This equipment allows the moment caused by a fluid thrust on a wholly or partially submerged plane surface to be measured directly. This surface can be tilted.
A PVC quadrant is hinged on a shaft pivoted on knife edges which coincide with the quadrant center. The quadrant position is adjustable relative to a balance arm such that the submerged plane surface can be tilted by changing the lock pin position. A depth scale is indicated on the quadrant. When the quadrant is immersed in water, there are hydrostatic forces.
The balance arm has an adjustable counter balance and weights with a hanger. The quadrant is mounted on top of a clear acrylic tank which allows water to be admitted and drained to required level by a valve. The tank rests on adjustable footings and a bull’s eye level is provided.
