A series of straight pipe sections, bends and different air inlet shapes that are equipped with static pressure tapings to allow air pressure drops due to pipe friction to be measured at a range of air velocities.
The air flow rate may be measured using a standard orifice using the differential pressure.
It is designed to determine the swelling pressure developed by soil specimens moulded to desired densities at knows moisture contents when soaked in water. The load applied to restrain the swelling is transferred to a load measuring proving ring through a perforated swell plate and a load transfer bar. The proving ring is attached to the lead screw of hand operated load frame. A soaking tank is provided for saturating the specimen and the base of the mould has channels and radial grooves with connecting holes it consists one each of : 1.Load Frame, Hand Operated, Capacity 50 KN (5,000 kgf) 2.Mould, 100mm dia x 127.3mm height (1,000ml volume) with base plate and collar 3.Proving Ring, with integral boss, high sensitivity 2.5KN (250 Kgf) capacity 4.Dial Gauge , 25mm travel, 0.01mm least count Lid & receiver in G.I. frame for 300mm dia x 450mm dia sieves 5.Perforated swell plate, 100mm dia x 16mm thick 6.
