Technical description:
  •  The apparatus has been designed to introduce students to the fundamental characteristics of the behaviour of the particle system, in particular the relationship between the drag coefficient of falling particles and reynolds number. Particles covering a range of sizes and densities are supplied and the experiments are conducted by allowing single particles to fall through a number of different liquids contained in a vertical glass tube. The rate of fall of the particle is determined by timing their passage between two marks on the walls of the glass tubes. Observation of the particle movement is aided by the provision of a shielded fluorescent tube light mounted on the backboard. Particles can be removed from the bottom of the tubes without the necessity of draining the liquid. A valve system is provided at the bottom of each tube to allow the particles to be removed with the minimum loss of liquid.
Learning objectives/experiments
  •  To measure the drag coefficient and verify stokes law.
  •  To plot the graph between drag coefficient vs. Reynolds number.
  •  To study the motion of a solid particle through a liquid.
Required for operation:
  •  Electricity supply 100 watts, 220 v, 1 phase.
  •  Floor area 0.75 m x 1.5 m.
  •  Liquids of different viscosity.
Technical specifications
  •  Tubes : material borosilicate glass tube (3 nos.)
  •  Gate valves : 6 nos. (2 nos. On each tube)
  •  Stop watch : electronic.
  •  Steel and glass balls of different sizes will be provided.
  •  The set-up tube light arrangement for visualization.
Control panel:
  •  Standard make on/off switch, mains indicator etc.
Scope of delivery:
  •  1 self-contained “drag coefficient” apparatus
  • 1 instruction manual consisting of experimental procedures, block diagram etc

Technical description:
  • Helical coils are used for heating or cooling in process tanks. When a fluid flows through a curved tube, centrifugal force acting upon the various elements of fluid moving with different velocities causes secondary circulation. Secondary flow results in higher heat transfer characteristics. Further, secondary flow stabilizes the laminar flow leading to a higher critical reynolds number for transition from laminar to turbulent flow.
Learning objectives/experiments
  •  To determine the critical reynolds number of a fluid flowing through the coil.
  •  To compare pressure drop in helical coil with that in a straight pipe of same length, inside diameter and surface roughness.
Required for operation:
  •  Electricity 500 watts, 220 v, 1 phase.
  •  Floor area 1 m x 2 m.
Technical specifications
  •  Helical coil : material stainless steel dia – 12”
  •  No. Of turns : 14
  •  Coil tube dia : od 21mm, id 16mm (approx.)
  •  Sump tank : material stainless steel, capacity 50 ltrs.
  •  Water circulation : fhp pump, crompton/sharp make.
  •  Pressure drop measurement: by manometer
  •  Flow measurement : rotameter.
  •  Piping : gi and pvc
Control panel:
  •  Standard make on off switch, mains indicator etc.
Scope of delivery:
  •  1 self-contained “flow through helical coil” apparatus
  •  1 instruction manual consisting of experimental procedures, block diagram etc.

Technical Description:  

The set up is capable to study the loading and flooding characteristics. It is a packed column packed with Rasching Rings where the Air is counter currently fed to the column. Liquid holdup in the column increases the weight of column and also reduces the effective porosity of packing. This reduction in porosity decreases the gas velocity, increases the pressure drop and changes the value of mass transfer co-efficient. The water is fed from the top of the column and loading & flooding characteristic are observed on various flow rates of Air and Water. The apparatus is closed circuit type provided with suitable capacity tank, pump, necessary pipe lines walls & rotametres for water & air to measure the flow rate of fluids.
