Permeability is recognized as being the most important parameter in assessing concrete durability. The depth test is performed by drilling a hole 10 mm diameter x 40 mm deep, and plugged with a silicone rubber plug. The ingress of air and moisture into the concrete can cause corrosion of the steel reinforcement and lead to a deterioration in concrete strength. An hypodermic needle is passed into the stopper; the water permeability test is performed by measuring the time of absorption needed by the water introduced into the void by pressure. Therefore, a measure of the ease of movement of liquids and gases through the surface layer of the concrete is a better method of assessing the soundness and expected life of concrete than strength alone. Surface permeability tests can be carried out by clamping a stainless. For the air permeability test, a vacuum pressure is created in the void, and the time needed to rise this pressure is measured.

The Radial Heat Conduction accessories have been designed todemonstrate the application of the Fourier rate equation to simple steady-stateconduction radially through the wall of a tube.
Hardware Description:
The accessory comprises a soliddisk of material, which is heated at the centre and cooled at the periphery tocreate a radial temperature difference with corresponding radial flow of heatby conduction.
Six K-type thermocouples arepositioned at different radii in the heated disk to indicate the temperaturegradient from the central heated core to the periphery of the disk.
The arrangement, using a solid metal disk with temperature measurementsat different radii and heat flow radially outward from the centre to theperiphery, enables the temperature distribution and flow of heat by radialconduction to be investigated.
The heater power and the cooling water flow rate are controlled via,either from the front panel or from the computer software. These are controlledmanually.
A control valve permits the flowof cooling water to be varied, if required, over the operating range of 0-1.5l/min.
The cooling water flow rate ismeasured by a turbine type flow sensor .
An optional cooling water flowrate sensor Set 2 is available upon request for the connecting directly intothe service unit.
The radial distance between eachthermocouple in the disk is 10mm.
Quick-release connectionsfacilitate rapid connection of the cooling tube to a cold water supply. Apressure regulator is incorporated to minimise the effect of fluctuations inthe supply pressure.
This auxiliary pump is intended to be used inconjunction with the basic Hydraulics Bench. This accessory comprises a variable speed pumpassembly and independent discharge manifold interconnected by flexible tubingwith quick release connectors. The pump speed is varied by an inverter drive. An independent discharge manifold incorporates apressure gauge and flow control valve prior to a discharge pipe with diffuser. A compound pressure gauge is mounted on the pump inlet and a pressuregauge is mounted on the pump outlet. Themotor speed, output voltage and motor current can be monitored on the inverterdisplay. The auxiliary pump is mounted on a support plinthdesigned to be positioned on the floor besides the hydraulics bench, adjustable feet allowing levelling.

The DC motors are used in a wide variety of industrial drives, such as robots, machine tools, oil drilling rigs, mining, automotive systems, etc. On the other hand, DC generators are still in use in some power generatingplants. The real difference between DC motor and DC generator is the directionof power flow. All the DC machines have a reversible behavior: they aremotors up to a frequency that is characteristic of the construction parametersand is said synchronism frequency, beyond which they behave as generators. The electric machines bench has been designed to satisfy thefollowing basic requirements:
The plan activities
The economic advantage
The number of groups of students who must worksimultaneously
Their speed can beeasily adjusted in very fine increments ranging from standstill to rated speedand even above and their construction is made rather complex than their AC counterparts by the fact that they need a commutator, which reverses thedirection of current and fluxes to produce a net torque. The DC machines are driven from a DC power supply and theyare the most versatile of all rotating electrical machines.

Flocculation chemicals can be added to the rawwater in order to improve the flotation of the contaminants. The diatomiteprovided is suitable as a contaminant. Flotationprocesses are used to separate solids from a liquid. The flotation process mostcommonly used in water treatment is dissolved air flotation. The suspension tobe treated is placed in a tank. A pump transports the raw water, whichenters the flotation column via a vertical pipe. The air dissolves in the water under pressure. Part of the waterflows back to the pump via a bypass. The other part of the water enters apressure vessel filled with Pall rings. The height of the supply linecan be adjusted. The pressure vessel ensures asufficiently long dwell time to dissolve the air and to separate undissolvedair. A water circuit with pump is connected to the flotationcolumn. Two compressors supply air to the water circuit on the suction side ofthe pump.
The water then enters the flotation column from below via a valve. This causesa sudden drop in pressure to almost atmospheric pressure. The contaminants rise up in thecolumn together with the air bubbles. At the upper end of the flotation column,the contaminants enter a circulating channel. Since the solubilityof air increases with increasing pressure, the excess air forms small bubbles.The air bubbles accumulate on the contaminants.
