Laboratory Experiment on Venturi Meter and Orifice Meter

Venturi & Orifice Meter INTRODUCTION As we learned in the Impact Jet lab, the speed of a moving jet of water is proportional to the water’s velocity.  This is evident in a turbine flow meter, where the impact force of the water on the blades sets the rotor in motion.  Once there is a steady … Read More»

Comparison of Different Turbulent Models for Backward-facing Step Flow

Comparison of Different Turbulent Models for Backward -facing Step Flow Abstract A comparison of different turbulence model for flow over a backward facing Step is presented. A Reynolds number of 36,00 and an averaged velocity of 41.7 m/s was considered. The result was compared with data by Driver and Seegmiller.  The purpose of this paper … Read More»

The Quantum Hall Effect

THE QUANTUM HALL EFFECT Abstract The Quantum Hall effect (QHE) is the observation of the Hall effect in a two-dimensional electron gas system (2DEG) such as graphene and MOSFETs. It represents good example of physical systems where quantization effect could be observed microscopically as a result of the interplay of the topology, interactions of electron … Read More»

History of Modern Cosmology and the Rise of the Big Bang Model

History of modern cosmology/ Rise of the Big Bang Model: Soon after Einstein had formulated the general theory of relativity, in 1917 he postulated that the universe is homogenous, isotropic, static, with a constant mean mass density and curvature of space. However, this model was not permitted by his field equations as they suggested that … Read More»

Do the Laws of Physics Lie?

Do the Laws of Physics Lie? Cartwright (1983) claims that the laws of Physics lie. There is causal power of things and specific interpretation of objects, which make the author reconsider the basic concepts of physics. First, the core idea of Cartwright is to underline the main goal of physics or the description of things … Read More»
