After each measurement, readjust the water level to the 6 inch level. Use the last water level drop to calculate the percolation rate. In sandy soils or soils in which the first 6 inches of water added after the soaking period seeps away in less than 30 minutes, make water level measurements at 10 minute intervals for a 1 hour period. Use the last

The sand density varies upon several factors and its conditions. A normal loose dry sand has the density of 1442 kg/m 3. Sand Density Formula: The ratio of mass of the sand to the volume of calibrating container gives you the density of sand. Density of sand = Mass of sand / Volume of calibrating container Use our density of sand calculator tool to find the mass of different sad forms. To ...

Point measurement Point infiltration measurements are normally made by applying water at a specific site to a finite area and measuring the intake of the soil. There are four types of infiltrometers: the pondedwater ring or cylinder type, the sprinkler type, the tension type, and the furrow type. An infiltrometer should be chosen that ...

Dust concentration measurement

Dust concentration measurement

For that the measured object can be analysed directly in exhaust gas channel (insitu measurement) or a partial volume flow is collected and fed into a measuring device (extractive sampling). As result of the insitu techniques, the measurement signals derive from the direct interaction of light or a triboelectric probe with the dust particles in the exhaust gas channel.
