Rotor spinning is known for high production rates and uniformity of the resulting yarn. However, determining machine components which will produce the optimum process parameters such as airflow speed to result in the best combinations of yarn quality and uniformity can be a difficult task. The aim of this study is to simulate and analyze the airflow characteristics in rotors with U and V grooves during the rotor spinning process. The results obtained showed that airflow speed resulting from a rotor with the V groove is higher than that of U type. As a result, the static pressure resulting from the use of the V type groove is lower than that of U groove.

High Possibility

<p>The use of the pipeline is the safest method in sending oil and gas from one area to another in oil and gas transportation system. The only challenge is to keep the pressure drop in the pipeline as small as possible to avoid high pressure differences. This pressure difference can result in reduced production flow rate and affect the flow pattern in the pipeline. The condition can lead to high possibility of a slug on pipelines that drain multiphase flow. Slug becomes one of the main concerns transport processes multiphase flow in pipelines. The emergence of slug in the pipeline could cause an unstable hydrodynamic conditions will continue to affect the liquid level in the inlet separator and cause flooding in the separator. Some of the conclusions mainly on the diameter of the pipeline, the size of the slug catcher and the size of the separator obtained from the calculation based on the study of literature and simulations with software HYSIS and OLGA. Design slug catcher to accommodate the number of processes that occur in the production transportation of X oil and gas field through a pipeline 10 inches along the 12 km with 20.68 m3 volume of slug using 3 (three) finger with diameter 28 inches and length of 10 meters each. For the separation process of oil and gas in the first five (5) years of X oil and gas field  which has a high production of oil and condensate will require separator with 30 inches diameter, seam to seam height of 8.1 ft or 2.5 meters, with retention time for 2 minutes and the 3.2 slenderness ratio of the vertical separator.</p>

Macroscopic Analysis

The split, fall, collapse and severe diapirism of tube body happened on one of the tubing used in the gas well of high pressure and high production in the process of the trial extraction. This paper aims to explore the reason of its occurrence through the research of the macroscopic analysis, mechanical and chemical property test and microscopic metallographic test study. The result of the research shows that the multiphase flow of gas, liquid and solid in the tubing may produced an instantaneous negative pressure and increased the possibility of the tubing being collapsed in the process of gas testing and production.Then it resulted in clogging, severe ablation, thinning wall and piercing in tube and finally the tube broke because of the low tensile strength.

Abstract Muxagata, E., Amaral, W. J. A., and Barbosa, C. N. 2012. Acartia tonsa production in the Patos Lagoon estuary, Brazil. – ICES Journal of Marine Science, 69: 475–482. Acartid copepods are abundant in estuaries, harbours, and semi-enclosed waters. A monitoring programme with the objective of evaluating copepod production, particularly that of Acartia tonsa, the dominant taxon in the Patos Lagoon estuary, was implemented. Zooplankton samples are collected monthly from two fixed locations with bongo nets 30 cm in diameter with nets of 90 and 200 μm mesh. Over a full year, 33 quantitative samples were analysed; copepods represented 40% of the organisms collected with the 90-μm mesh. Adults and copepodites of A. tonsa accounted for ∼19% of the total copepod fauna at both locations. Daily production rates of A. tonsa were calculated as 0.40 mg C m−3 d−1 for the inner estuary and 3.65 mg C m−3 d−1 in the channel. The value of 1 333 mg C m−3 year−1 calculated for A. tonsa at the channel station is very high relative to the situation in other estuaries, indicating that the estuary has a high production of copepods.
