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 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 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/ 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
A Change of Heart Abstract The essential part of the circulatory system is the heart. In other words, any organism cannot live without this organ properly functioning. The duties and mechanisms of these functions must be performed correctly or else there could be potential serious consequences to the rest of the body. … Read More

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

Synthesis Techniques for Nanoparticles Synthesis method being used for the preparation … Read More
The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic “elements” of … Read More
