The Effect of Design and the Accelerated Wear Test of Agricultural Nozzles on the Resulting Droplet Size
...Show More Authors
Abstract<p>The change in the size of the droplets during the pesticide application process could have a negative impact on the percentage of drift or the losses of pesticides to the environment. One of the factors that could affect the droplet size produced from a single nozzle is the internal design of the nozzle itself, in addition to the wear of the nozzle orifice as a result of the usage time. In this research, three types of nozzles with different internal designs were used (Turbo TeeJet (TT), Turbo TwinJet (TTj 6011003), and Drift Guard (DG 11003)). The nozzles were subjected to an accelerated wear test for one hundred hours, and different droplet size parameters (Dv 0.1, Dv 0.5, Dv 0.9), relative span (RS), and Sauter mean diameter (SMD) were measured during and after this test. The measurements were made using the Sympatec HELOS-VARIO/KR device in fifteen positions along the spray swath. The results of the study showed that the droplet size (Dv 0.5) generally increased for the DG 11003 and TTj 6011003 nozzles after the accelerated wear test (worn nozzles), while there was a decrease in Dv 0.5 for the TT 11003 nozzles. The DG 11003 nozzles (before and after the wear test) had the highest percentage of droplets with a size smaller than 150 μm (%< 150 μm) compared to the TT 11003 and TTj 6011003 nozzles. Moreover, the %< 150 μm was higher in the middle position of the spray swath for the three types of nozzles and the new and worn nozzles.</p>

The Impact of Matrix Acidizing on the Petrophysical Properties of the Mishrif Formation: Experimental Investigation
...Show More Authors

Matrix acidizing is a good stimulation process in which acid is introduced into the reservoir near the wellbore area via the wellbore or coil tubing. In the oil industry, formation damage is a prevalent problem. Bypassing wellbore damage by producing wormholes in carbonate reservoirs is the main purpose of acidizing the matrix of the formation. When doing lab tests, scientists are looking for a wormhole-inducing injection rate that can be used in the field. Meantime the ongoing works on the Ahdeb oil field's Mishrif reservoir, several reports have documented the difficulties encountered during stimulation operations, including high injection pressures that make it difficult to inject acid into the reservoir formation; and only a few

Apparent Viscosity Direct from Marsh Funnel Test
...Show More Authors

Accurate and simple techniques for measurement of fluid rheological properties are important for field operations in the oil industry. Marsh Funnels are popular qualitycontrol tools used in the field for drilling fluids and they offer a simple, practical alternative to viscosity measurement. In the normal measurements, a single point (drainage time) is used to determine an average viscosity; little additional information is extracted regarding the non-Newtonian behavior of the fluid. Here, a new model is developed and used to determine the rheological properties of drilling muds and other non-Newtonian fluids using data of fluid density and drainage time collected from a Marsh Funnel as a function of viscosity. The funnel results for viscos

Analyzing the impact of exchange rate fluctuations and inflation on the GDP in Iraq using the modern methodology of Cointegration for the period (1988-2020)
...Show More Authors

     The research aims to analyze the impact of exchange rate fluctuations (EXM and EXN) and inflation (INF) on the gross domestic product (GDP) in Iraq for the period 1988-2020. The research is important by analyzing the magnitude of the macroeconomic and especially GDP effects of these variables, as well as the economic effects of exchange rates on economic activity. The results of the standard analysis using the ARDL model showed a long-term equilibrium relationship, according to the Bound Test methodology, from explanatory (independent) variables to the internal (dependent) variable, while the value of the error correction vector factor was negative and moral at a level less than (1%). The relationship bet
