Flow characteristics of fluid and its effectiveness on orifice plate using pneumatic proportional control

Abstract

A number of studies on effect of temperature on the flow characteristics of various fluids have been carried out. The aim of this work was to examine the flow characteristics of hexane upon the influence of temperature as well as the effectiveness response of orifice plate using pneumatic proportional control. Knowledge of the past on temperature impact as one aspect of the information set held by various scientific and a well established finding in engineering is that changes in composition can change the effect of temperature on the flow characteristics of hexane in a flow line system. The particular aspects of temperature impact on the research work highlighted are density, viscosity and pressure characteristics. The effect of temperature on flow characteristics of hexane was examined within the temperature range of 283 to 323 K and Bernoulli's equation knowledge of the past was used in developing the model for this paper. The mathematical models developed were simulated using the numerical concept of polynomial expression of the best fit. The effects of temperature on the functional parameters were examined and proportional gain at various error range of E = 0.1 to 0.5 were considered during the investigation. These effects on the variation of the results were attributed to the temperature, flow characteristics of the hexane and its effectiveness on orifice plate using pneumatic proportional control.

Model prediction on the characteristics of dipole atoms: the concept of Schrodinger’s equation

“…Later, this interest was fueled by the observation that electron capture by a frozen molecule with a permanent electric dipole moment could takes place if the dipole moment exceeds a certain minimum critical value. Another source of interest came from early experimental work on the scattering of low energy electrons by such molecules, which exhibited peculiar features moreover, the electron binding properties of polar molecules have been the topic of considerable theoretical and experimental interest (Ukpaka and Ndor, 2013). It has been shown that the electron dipole field is capable of supporting an infinite number of bound states for an electron if the dipole moment is greater than the critical values 0.6393 au.…”
