ALAT PERAGA PERMEABILITY / FLUIDISATIN ( TEKNIK LINGKUNGAN)
Alat trainer Permeability atau fluidisation ini didesain agar para pelajar dapat belajar untuk mengukur dan mengerti karakteristik flow atau aliran yang melalui dasar partikel-partikel
Alat ini bisa juga digunakan sebagai media pengajaran water dan wastewater filtration

DESCRIPTION:

-Permeameter: This device is basically a transparent acrylic cylinder that encases the soil specimen to be tested. There are four piezometer taps located along the vertical axis of the cylinder, these will measure the total head at specific point in the soil specimen. The permeameter cell also has pots in the top and one purge valve placed in the top
-2 Filter Metallic Manometer: These are transparent tube and will allow the observation of total head.
-Bourdon Manometer: The equipment also has two bourdon manometers.
-Constant-Head supply device: This is a tank, with an overflow, help up on a stand above the permeameter. A flexible tube connects the bottom outlet of the tank to the bottom inlet of the flowmeter
-Flowmeter: It allows us to measure the water flow. The outlet is connected to the collector.
-Distribution Collector: The distribution allows to determine the direction of the liquid, upper to bottom or vice versa.
-Piezometer taking collector: It allows selecting the piezometer reading in the cylinder between four allowed configuration.

PRACTICAL POSSIBILITIES:
1.-Pressure drop measurements and correlations for flow throught packed beds.
2.-Calculate the density of each specimen,
3.-Calculate the relative density of specimen mixing.
4.-Study and verification of .
Carman-Kozeny' s equation.
5.-Calculation the void ratio.
6.-Determine the permeability constant ( Darcy' s law)
7.-Observation of a liquid fluidised bed.
8.-Attrition test.
