MOMENTUM TRANSFER LABORATORY MMT-001 EQUIVALENT LENGTH OF PIPES
The apparatus is
designed to illustrate the quantitative relationship between rates of flow
& pressure difference. Power
requirements for the system can thus be established. M.S. water pump of 300 Ltr. capacity water measuring tank of 200
Ltr. capacity & ½ HP pump set will be provided. In the system following fittings are considered. MMT-002 FLOW THROUGH FLUIDISED BED
For air or water
fluidisation in a 50mm glass tube, 40 mm long with all fittings connected to
orificemeter. The air blower will be
connected to the open assembly with control valves & it is liquid system,
liquid fluidisation will be shown by using centrifugal pump collecting tank
etc. MMT-003 FLOW THROUGH HELICAL COILS
The setup consists of a
tank & a small centrifugal pump with rotameter to measure the flow of water
& a coil of 15 cm dia. & 10 coils of ½” ID with a gate & pressure
& flow measuring device suitable to above test rig. MMT-004 FLOW THROUGH NON-CIRCULAR PIPES
The setup consists of a
parallel configuration of six pipe sections with ball valves to channel flow of
water into any one pipe section at a time.
Each pipe section will
provided with unions at both beds to enable easy removal of the entire
section. The length removal of test
section in each case will be about 1.5 m. & columning length of atleast 0.2
m. will be provided on the upstream end.
Pressure tappings will be provided.
The tapping will be provided to enable connection of any pair to tapping
to the manometer. Vent cocks will be
provided at the entrance & a exit sections & also on the manifold to
enable purring of air from system. A
mercury U tube manometer & a carbon tetra chloride manometer is
provided. Decolam backing board. The assembly with the backing board, will be
supported on a frame & provided with sturdy leveling screws. The equipment will be self contained &
will include a floor standing service module containing a motor driving pump (
0.5 HP ) provided with a non-return valve, pump tank, volumetric flow measuring
collecting tank, level gauge & necessary inter connecting pipe work. A direct on line motor starter will be
provided on the board. MMT-005 FLOW THROUGH PACKED BED
The equipment consists
of a glass tube with plastic beads packing supported on stainless steel mesh
held between two bottom flanges. A
similar wire mesh is provided at the top also to prevent solid being carried over. For uniform liquid distribution a known
columning length is provided at the bottom.
A mercury manometer is
connected to the pressure taps at the bottom & top of packed bed to measure
the bed pressure drop. A centrifugal
pump is used for circulating water through the bed. A drain valve is provided at the bottom for darning water. MMT-006 JOULE THOMSON CO-EFFICIENT EXPERIMENT
In the apparatus the
fluid whose Joule Thomson co-efficient is to be measure is allowed to expand
steadily through a porous plug. The
plug & adjacent piping are thermally insulated. The fluid inlet pressure is varied for obtaining a plot of exit
pressure Vs exit temperatures. The
experiment is repeated for different inlet conditions MMT-007 LAMINAR FLOW ANALYSIS TABLE
The set up consists of
parallel glass plates of 100 x 780 mm size, provided at both ends one FRP tanks
of 7780 x 200 mm size to act as source tank & sink tank. Necessary vales, openings, pipes & tubes
dye breaker & its tubing are incorporated.
The unit shall have a panel & necessary supporting frame MMT-008 PRESSURE DROP IN TWO PHASE FLOW
It consists of a tank in
which water is pumped to a straight pipe.
Part of the lone is of perspex.
Manometer taps are attached to the perspex tube. Water flow rate is measured by rotameter is
provided to measure air flow rate. The
flow rate of water & air controlled by means of globe valve. Pressure gauges are provided. The mixture of air & water leaving the
pipe enter the separator & the water is led to the drain. MMT-009 SPOUTED BED
The apparatus consists
of a vessel open at the top & filled with relatively coarse particulate
solids. Fluid is injected vertically
through a centrally located small opening at the base of the vellum. At a certain fluid injection rate, the high
velocity jet causes a stream of particles of rise rapidly in a hollowed center
core within the bed of solids. These
solids after reaching somewhat above the peripheral bed level rain back into
annual region between the hollowed core & the column wall, the where they
slowly downward as a loosely packed bed.
As the fluid travels upward it flashes out into the annulus. A systematic cyclic pattern of solids
movement is established giving rise to a termed the spouted bed. The central core is called a spout & the
peripheral annular region is termed the annulus. Spouted beds display characteristics which cannot be realised in
conventional fluidised beds. MMT-010 THREE PHASE FLUIDISATION
The equipments consists
of a vertical prespex tube with a conical bottom. There is provision for introducing liquid & gas from the
bottom. Tube is filled upto about 1/ |
