Dynamic voltage scaling

Two factors are required for proper operation of a gas turbine. One is expressed by Newton’s third law. The other is the convergent-divergent process. Convergent means approaching nearer together, as the inner walls of a tube that is constricted. Divergent means moving away from each other, as the inner walls of a tube that flares outward. Bernoulli’s principle is used in this process. The venturi of the common automobile carburetor is a common example of Bernoulli’s principle and the…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…

This project consist of Numerical and Computational Fluid dynamics analysis of heat transfer enhancement and the corresponding pressure drop over a flat surface equipped with cylindrical cross-sectional perforated and solid pin fins in a rectangular channel. The channel had a cross-sectional area of 250-100 mm2. The experiments covered the following range: Reynolds number 13,500–43,500, the constant clearance ratio (C/H) = 0, the inter-fin spacing ratio (Sy/D) 1.944 and 3.417 for Staggered…

Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the…

Abstract:The second order rotatory theory of hydrodynamic lubrication was founded on the expression obtained by retaining the terms containing first and second powers of rotation number in the extended generalized Reynolds equation. In the present paper, there are some new excellent fundamental solutions with the help of geometrical figures, expressions, calculated tables and graphs for the porous bearings in the second order rotatory theory of hydrodynamic lubrication. The analysis of equations…

Ultrasonic interferometer Working principle An ultrasonic interferometer is a simple and direct device to determine the ultrasonic velocity in liquids with a high degree of accuracy. An ultrasonic interferometer is used to determine the accurate ultrasonic velocity in liquids. The principle used in the measurement of velocity is based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of the…

Imagine this, you are standing in line to the world’s largest roller coaster. Your stomach is tying itself in knots just watching other people go up and down, back and forth, and upside down. You can hear them shrieking with every loop in the ride and you cannot wait to experience it for yourself. The want to get the endorphins rushing through your body, it is a natural high. This roller coaster is only an example of one way to get that natural high. For me, I search for anything crazy to allow…

small, smoke column will not create in the atrium and floding flow will not occur to vent smoke. Figure ‎2.8 Flow at the early stage of adjacent floor fire[13]. Table ‎2.4 Conditions of each simulation [13]. By watching the calculation results dynamic display, then the time and location of the flooding flow can be obtained.Floding flow did not occur till the simulation end time at 800 second in the atria with size 11×11×27m and 12×12×27m. In the range of designed HRR of fire (100 kW to 2000…

believe I took the role as the analyzer conceptualizer by stepping up and letting the group know what was expected from us. On the other hand, when it came to utilizing the items that were given to us by making an inventive presentation of the group dynamics we agreed upon, my others members stepped up as planner and doer. From activities such as these I learned that I am not…
