However, the calculation results of the maximum crack width following GB 50010-2010 and EN 1992-1-1:2004 were considerably conservative. In the context of GB 50010-2010, a revised formula for the crack width is proposed with modifications to two major factors: the average crack spacing and an amplification coefficient of the maximum crack width ...

Agricultural Anaerobic Digesters: Design and Operation

Dec 01, 2016· The sludge auger was 6 in (150 mm) in diameter by 28 ft (8.5 m) long. It was powered by a direct-coupled submerged hydraulic motor operated at 60 rpm, which required approximately 0.5 hp (0.35 kW). The hydraulic motor that powered the sludge-removal auger and hydraulic cylinders were operated by an electrically driven hydraulic pump.

What is Center of Mass and Center of Gravity?

🕑 Reading time: 1 minute The center of mass of a system of particles is a specific point at which, for many purposes, the system''s mass behaves as if it were concentrated. In another word, center of mass is the point at which the distribution of mass is equal in all directions, and does not […]

Radar Cross Section - an overview | ScienceDirect Topics

The RCS of a complex target that is large compared to a wavelength is highly dependent on the aspect angle. A small change in the aspect angle can cause the RCS to fluctuate several tens of decibels.. 10.4.2 RCS Enhancement and Reduction. In some civilian applications, such as navigation, it is desirable to enhance the radar echo of the object so that it can be easily detected or tracked.
