Rate Analysis of Excavation in Earthwork -Calculate Excavation Cost

Then its capacity considered is ( (1x10)/0.04125) = 242.4242 m 3 / day. That means, a hydraulic excavator can excavate 242.4242 m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as: No. of days required for 10m 3 excavation = 10/242.4242 = 0.04125 days.

The Defining Series: Basic Well Log Interpretation

The bulk density (rhob or Pb) of a formation is based on the ratio of a measured interval''s mass to its volume. In general, porosity is inversely related to the density of the rock. The Pb measurement is derived from the electron density of a formation. This measurement is obtained by a logging device that emits gamma rays into the formation.
