The purpose study is to substantiate the parameters of air flow when exiting casing and working parts fan. In course studies, pressure velocity were determined by an improved Pitot-Prandtal tube. experimental influence speed fan wheel sprayer on window part was studied. It found that from increases average 65 Pa 152 number revolutions increased 800 r/min 1200 r/min, 5.5 times 1600 r/min. coming...

Bay laurel is an evergreen, commercially grown and expensive ornamental pot plant, which is susceptible to different pests like aphids, scale and lerp insects, thrips, caterpillars of codling moth and sooty moulds. Recently, caterpillars of the Mediterranean carnation leafroller (Cacoecimorpha pronubana) cause more and more problems. These pests can lead to important financial losses for the gr...

In this article, a new approach for the efficient design of quantum-dot cellular automata (QCA) circuits is introduced. The main advantages of the proposed idea are the reduced number of QCA cells as well as increased speed, reduced power dissipation and improved cell area. In many cases, one needs to double the effect of a particular inter median signal. State-of-the-art designs utilize a kind...

A fan is a set of edges with a single common endpoint. A graph is fan-crossing if it admits a drawing in the plane so that each edge is crossed by edges of a fan. It is fan-planar if, in addition, the common endpoint is on the same side of the crossed edge. A graph is adjacencycrossing if it admits a drawing so that crossing edges are adjacent. Then it excludes independent crossings which are c...

Electric Fans are very commonly used in the industries, domestic applications and in tunnels for cooling and ventilation purposes. Fan parameters estimation is an important task as far as the reliable operation of a fan system is concerned. Basically, a fan is mainly consisting of a single phase induction motor and therefore fan system parameters are essentially the electrical parameters e.g. r...

We propose definitions of QAC, the quantum analog of the classical class AC of constant-depth circuits with AND and OR gates of arbitrary fan-in, and QACC[q], where n-ary MODq gates are also allowed. We show that it is possible to make a ‘cat’ state on n qubits in constant depth if and only if we can construct a parity or MOD2 gate in constant depth; therefore, any circuit class that can fan ou...

In this paper, numerical and experimental investigations on an axial-flow fan with grooved/double-sectional blades are performed to improve its performance in terms of volume flow rate and noise at a local operating point. The target fan is used to cool a mechanical room of a household refrigerator. However, it is found that the target system has more resistance than that for which the fan is o...

The layout of ceiling fans in buildings is challenging because the need to co-ordinate with other elements space, and resulting airflows within occupied space interact furniture. This study conducted detailed air speed measurements four different room sizes, furniture configurations, fan types, ceiling-fan-to-floor-area ratios. We measured speeds across spaces at heights while varying operation...

introduction alluvial fans are depositional landforms developed on a confined channel emerged from a drainage basin, i.e. between a mountain range and a plain. an alluvial fan is a fan- or cone-shaped deposit of sediments crossed and built up by streams. if a fan is built up by debris flows, it is properly called a debris cone or colluvial fan. these flows come from a single point source at the...
