Calculation of Some Crude Oil Flow Parameters in A Cylindrical Tube and Their Modelization in Small and Great Variable Radius

/in /by

In this work, we establish the kinematic of flowing of crude oil inside a cylindrical tube which is rare in the literature. From velocity expression, we find kinematic. Pressure, temperature and heat distribution of crude oil flowing are also find from equations in the literature. Silmilation of these expressions shows that Kinematic of crude oil is similar to a flow of a fluide with a small viscosity what is true in the reality. Velocity of crude oil is not similar in any points during the flowing but increasing and decreasing according to the position point and seams like to be more fast in the border than in the center with a small radius and more fast in the center than in the border with a great radius. Temperature of the crude oil is not similar in any points during the flowing. It is more elevated in the the border than in the center. Pressure in small radius is more important in the center than in the border contrarily in great radius. results are more conformable in the reality in small than in great radius. Results of the heat is more conformable in the reality in small than in great radius.

The Effect of Pressure, Opportunity, Rationalization, Religiousness on Fraud Behavior (PT. Mayora Indah Tbk Jatake 1)

/in /by

This study aims to examine the effect of pressure, opportunity, rationalization, and rationalization on employee fraud at PT Mayora Indah Tbk Jatake 1. This type of research is classified as survey research with a quantitative approach. The population in this study were employees of PT Mayora Indah Tbk Jatake 1. The research sample was determined by purposive sampling method so that a sample of 88 was obtained from the questionnaires. Data was analyzed by using multiple regression, intention to commit employee fraud as the dependent variable and pressure, opportunity, rationalization and religion as independent variables. The results of this study indicate that: (1) pressure has a significant positive effect on the intention to commit fraud, (2) opportunity has a significant positive effect on the intention to commit employee fraud, (3) rationalization has a significant positive effect on employee fraud intentions, (4) religion has a significant negative effect on employee fraud intentions. So it can be concluded that opportunity, opportunity, rationalization, and religion have a significant influence on the fraudulent intentions of employees of PT Mayora Indah Tbk Jatake 1.
