What is the significance of critical stress with respect to the structure of concrete?
What is the significance of critical stress with respect to the structure of concrete? Macroscopically, critical stress appears to be related to strengths of concrete under short-term, repetitive and long-time loading, and to fracture toughness, while microscopically, critical stress seems to indicate the beginning of significant slow crack growth. What is FC in reinforced concrete? […]

What purpose did the electrically charged plates have in the oil drop experiment?
What purpose did the electrically charged plates have in the oil drop experiment? Millikan oil drop experiment: The purpose of Robert Millikan’s oil drop experiment (1909) was to measure the electric charge of the electron. He did this by carefully balancing the gravitational and electric forces on tiny charged droplets of oil suspended between parallel […]
What are the characteristics of complex adaptive systems?
What are the characteristics of complex adaptive systems? Complex Adaptive Systems are characterized by a high degree of adaptive capacity, giving them resilience in the face of perturbation. Other important properties are adaptation (or homeostasis), communication, cooperation, specialization, spatial and temporal organization, and reproduction. What is complex adaptive systems theory? Complex adaptive systems thinking is […]
Is a centrifugal pump self priming?
Is a centrifugal pump self priming? Most types of positive displacement pumps are self-priming but care must be taken to avoid overheating, seal wear or cavitation during the dry-running, priming phase. Centrifugal pumps can be modified to be self-priming with a surrounding ‘tank’ to retain some of the fluid. How is priming done in centrifugal […]

How is Reynolds number defined as?
How is Reynolds number defined as? The Reynolds number is the ratio of inertial forces to viscous forces. The Reynolds number is a dimensionless number used to categorize the fluids systems in which the effect of viscosity is important in controlling the velocities or the flow pattern of a fluid. What is Reynolds number in […]
