Value Estimation Of California Bearing Ratio From Hand Cone Penetrometer Test For Pekanbaru Soils

open access: yesJurnal Teknik Sipil, 2019
In practice, the design of pavement is commonly based on the California Bearing Ratio (CBR) test. This research was performed to study local correlation between Hand Cone Penetrometer (HCP) tests to the field CBR value.

Evaluation of Subgrade Soils using California Bearing Ratio (Cbr) in Parts of Rivers

open access: yesJournal of Applied Sciences and Environmental Management, 2014
Subgrade soils are characterized by their resistance to deformation under load, which can be a measure of strength (stress needed to break a material) or stiffness (the relationship of stress and strain in the elastic range or how well a material is ...

Forces on Centrifugal Pump Impellers [PDF]

open access: yes, 1985
Forces are exerted on a centrifugal pump impeller, due to the asymmetry of the flow caused by the volute of diffuser, and to the motion of the center of the impeller whenever the shaft whirls. Recent work in the measurement of these forces as a function
