The specimens are submitted to hydrostatic stress for a pre-set period. The water permeated through the test specimen is directly collected and measured into a graduated cylinder. It is therefore possible to determine the permeability coefficient in cm/sec. by the attached formula. The equipment consists of a strong metallic frame holding four cells which are hot-galvanized for anti-corrosion protection. Automatic Concrete Water Permeability Apparatus At Four Cells fully automatic apparatus is designed to carry out water permeability tests on cubic concrete specimens max.150 mm side and cylinder specimens max.160 mm diameter. Each cell includes a pressure control manometer.

The steam bench incorporates four similar mild steel tubes, each connected to a common steam supply via an inlet regulating valve and a common blowdown line via an outlet valve. Two of the tubes are unlagged but have differing finishes, namely a painted finish and a chromium plated finish respectively. Lagging Efficiency Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The measured temperatures are displayed on an analogue temperature meter via a selection switch. From measurements of temperature and condensate levels over a period of time, students are able to calculate the lagging efficiency and the coefficient of thermal conductivity of the lagging. The remaining two tubes are lagged, one with glass fibre webbing tape and the other with a pre-formed fibre glass insulation jacket. Each tube is fitted with a sight glass and scale to enable condensate to be measured.

The impulse swirl meter uses a swinging honeycomb type matrix which is restrained from rotation by a strain-gauged load cell to totally arrest the angular swirl component thereby measuring the resultant angular impulse as a torque. Earlier methods of measuring swirl such as swirl vane meters, were dependent on the velocity profile of the air stream, whereas the impulse type of meter overcomes this limitation by responding to the total angular momentum flux in the swirling air flow.

It is therefore possible to control the speed of the forward and the rear dynamometer independently from each other. All 3 CRP dynamometer types have separate driveshafts for the forward and rear dynamometer to facilitate the connection of two motors. Alternatively, the two driveshafts can be connected through a gearbox normally with a transmission ratio of1:1 so that it is possible to drive both the forward and the rear dynamometerat the same speed in opposite directions, from one motor.
