5. A permeameter of 8 cm diameter contains a sample of length 35 cm. Attachments are made it to enable conducting either constant head test or falling head test. The stand pipe used for conducting falling head test has a diameter of 2.5 cm. When constant head test was conducted the loss of head was 100 cm measured on a length of 25 cm. If the rate of flow was 2.7 cc/sec, calculate the coefficient of permeability of soil. If a falling head test is conducted on the same sample in the permeameter find the time taken for head to fall from 150 cm to 100 cm.

Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.
