FLOW THROUGH HELICAL COIL MAKE : CREATIVE LAB MODEL NO:CLMTL-05
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.
EXPERIMENTATION:
To determine the critical Reynolds number of a fluid flowing through the coil.
To determine the friction factor for flow of water through helical coil.
To compare Pressure drop in helical coil with that in a straight pipe of same length, inside diameter and surface roughness.

DRAG COEFFICIENT APPARATUS MAKE : CREATIVE LAB MODEL NO:CLMTL:06
 
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.
EXPERIMENTATION:
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.
Utility required    
Electricity supply 100 watts, 220 V, 1 Phase.
Floor Area 0.75 m x 1.5 m.
Liquids of different viscosity.
Technical detail
Tubes (3 Nos.)  Material Borosilicate Glass tube.
Gate Valves  6 Nos. (2 Nos. on each Tube)
Stop Watch  Electronic.
Instruction Manual will be provided along with the Apparatus
Steel and glass balls of different sizes will be provided.
The whole set-up is well designed and arranged in a good quality painted structure having the tube light arrangement.
 

SEDIMENTATION STUDIES APPARATUS MAKE : CREATIVE LAB MODEL NO:CLMTL:08
DESCRIPTION
Sedimentation is the separation of solid particles from fluids under the gravitational force. When a solid particle moves in a fluid. Then a number of forces are acting on it:
1. The gravitational force, acting downward.
2. The buoyant force, acting upward.
3. The drag force, acting upward.
 When a particle fall in a fluid under constant force, e.g. force of gravity, then particle accelerates for some time, but when the accelerating force equals the retarding force (Buoyant force and Drag force) then the resultant force acting on the particle will be zero, and particle quickly reaches velocity, which is the maximum attainable under the circumstances and which is called the terminal velocity. When slurry is prepared in a container and then allowed to remain undisturbed for some time, four settling zones will appear as below:
 A Supernatant Layer
B Slurry Zone 
C Transition Zone
D Concentration Sludge Zone.
With the passage of time, the height of the different zones will vary and ultimately zone A of clear liquid and zone D of the sludge will be left. When all the solid particles settle in zone D, then this is critical stage and after this no settling takes place. With further passage of time, the height of the zone D will decrease due to the compression of the sludge on account of its own weight. Settling can be free settling or hindered settling. But most of the slurries settle under hindered conditions. Free settling is that in which the motion of one particle is unaffected by the motion of the other particle while in case of hindered settling many particles are present so there is mutual interference in the motion of the particles and the velocity of motion or rate of settling is reduced.
 The present set-up with 5 Nos. of Borosilicate Glass Graduated Cylinders is designed to study the zone settling depending upon the concentration and characteristics of the particles. These cylinders can be easily removed for cleaning. Rate of change in height of the various liquids/solids interfaces with respect to time can be measured with the help of stop watch.

 i)      Effect of initial concentration and initial suspension height on sedimentation rates.
 ii)    Effect of particle size distribution.

HYDRODYNAMICS OF PACKED BED MAKE : CREATIVE LAB MODEL NO:CLMTL-02
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.
EXPERIMENTATION:

Water Circulation FHP Pump.
Flow Measurement Rotameters 2 Nos. (one each for air and water)
Pr. Drop Measurement Manometer
Instruction Manual will be provided along with the Apparatus
The whole set-up is well designed and arranged in a good quality painted structure.
