Microsoft Excel 2010 Formulas & Functions

Excel 2010 Formulas and Functions One of Excel's most useful features is that it allows users to create custom formulas to perform calculations on their data. Excel also contains built-in formulas called functions that make it easy to perform common calculations on data. Here you will find step by step tutorials, tips and shortcuts on how to use formulas and the common and less common functions available in Excel. Formula Basics Formulas in Microsoft Excel begin with an equal sign. The equal sign tells Excel that the succeeding characters constitute a formula. If you don't enter the equal sign, Excel will treat your entry as text and the calculation will fail. To show how formulas work, we'll begin with a simple exercise by selecting blank cell A1. Then type =5+5, and press Enter. Excel performs the calculation and produces a result of 10 in cell A1. Notice the formula bar shows the formula you just typed. What appears in the cell is the result; what appears in the formula bar is the underlying value, which is a formula in this case.

Use SIFs and Flexibilities in CAESAR II® - Paulin Research Group

Using SIFs and Flexibilities in CAESAR II® Use SIFs and Flexibilities in CAESAR II® The following methods are recommended for pipe intersections when the stress intensification factors (SIFs) need to be considered per ASME B31.3 Appendix D Note 12. Simple and comprehensive methods are described below for using SIFs and flexibilities in a pipe stress analysis. Simple Method 1. Insert in-plane and out-plane SIFs for the branch element as shown below (next page). 2. Specify the general intersection type on any of the elements framing into the intersection. CAESAR II will provide header SIFs. 3. Model the intersection using three pipe elements. Do not enter stiffnesses and do not use any rigid elements to define the intersection. Notes: 1. Use the typical intersection model with three beam elements (not rigid elements) framing into the common intersection point. 2. The SIF should be specified on the intersection node of the branch element (node 10120 on the element 10110 to 10120 in the example below). 3. Specify the intersection type and any other data that is applicable in CAESAR II. CAESAR II will automatically calculate B31 SIFs for the header elements. 4. Always check the CAESAR stress reports to be sure that entered SIFs are used properly. (Input values for ii and io override the effective section modulus calculation. Stresses (even at intersections) are calculated using (i)(M/Z) when the SIF is entered. 5. CAESAR II will properly orient the SIFs providing all three elements that frame into the intersection are pipe elements. 6. Users can override CAESAR calculated header SIFs also. FESIF calculates SIFs for header elements. These SIFs are often considerably lower than Code calculated values when branch to header diameter ratio (d/D) is much less than 0.5.

Pipe Stress Analysis - CADWorx, CAESAR II & PV Elite: Insider Blog

Caesar II servatively, resulting in a lot of money being wasted. Since the calculation model is already built-up, this feature is worth using. It includes seismic load evaluation, forced vibration, hammer loads, natural frequency, response spectrum, time history analysis, slug flow and more. Isogen is a performant solution for the consequent automation of piping isometric drawing production and the de facto standard CAD system for drawing piping isometrics included in Caesar II. All the relevant data can easily be picked and placed on an isometric output. Company profiles can be used to deliver high quality outputs. With the Isogen wizard I-Configure, all parameters can be simply chosen from a list of options. A preview is used to shift all the data into place. Experienced users can also use the Project Manager. After this setup, isometric drawings can be generated for different projects in the same professional quality. A lot of the features of Caesar II improve results and help users find the best engineering. For instance, the Expansion Loop wizard generates the best possible loop for a given value. All the different options are calculated and the best is chosen for each specific case. The seismic wizard transforms the data provided into simple G loads. A lot of hanger producers made their data available for Caesar II and the user just has to select one item of this information to get the best results in this mode. There is no need to import further data from other sources. The same easy option can be chosen for expansion joints — just choose a company and the wizard inserts all the relevant components into the model. Line numbers...

The Programs for Strength Calculation in Pipelines

This paper draws on ongoing PhD thesis “Piping optimization on the basis of strength condition analysis”. The paper is structured as follows. After an overview of the theoretical issues the paper will provide an overview of the programs analysis for pipeline construction. The paper considers the description of four different programs (START, RAMPA, LV pipe II, CAESAR II) for strength calculation. The programs are analyzed by standard, program developer, technical specs, language, application areas, graphics function, error checker and reports. to choose the configuration of pipeline and, at the same time, to avoid unnecessary pipeline complication. It is necessary to arrange the supports taken into consideration so that they do not reduce pipeline compensating capacity. Strength calculation allows finding correct solution for supports placements, their types and characteristics. Programs characteristic and comparison Requirements to technical calculation of program The main requirements to technical calculation of the program are considered in this part of paper. The program is supposed to calculate: Reactions, forces and moments in supports and connected equipment • Pipeline forces and moments • Displacements • Strength and stress calculations according to standard EVS-EN 13480 • Nozzle loads • Wind loads • Friction • Fatigue The main characteristics of strength calculation programs are given in Table 1....

Comparison of WiMAX coverage at 450MHz and 3.5 GHz

Comparison of WiMAX coverage at 450MHz and 3.5GHz Tomaz Javornik, Gorazd Kandus, Andrej Hrovat, Igor Ozimek Department of Communication Systems Jozef Stefan Institute, Jamova 39 Ljubljana, Slovenia tomazJavornikijssi, gorazd.kandus Abstract In this paper we calculate, analyze and compare area covered by radio signal based on WiMAX standard at two carrier frequencies, namely 450MHz and 3.5GHz in flat rural, hilly rural and urban environment. The channel model proposed by WiMAX forum has been applied as path loss model at 3.5GHz for cell coverage prediction, while at 450MHz the Longley-Rice model for rural areas and Okumura Hata channel models for urban area is used. The cell size prediction strongly suggests to limit the 3.5GHz frequency band to urban areas, where the higher system capacity is required, while in rural areas the 450MHz carrier frequency provide good compromise between coverage and system capacity. - the Index Terms- HPA, WiMAX, system capacity, calculation coverage INTRODUCTION T he provision of Internet access and broadband multimedia services to residential users via wireless communication systems attracted an increasing interest of the research community, service providers and the telecommunication industry. The WiMAX specifications [1], which are a subset of IEEE 802.16 standard, seems to be the winner for providing a wireless access in urban, suburban and rural environment with non line of sight (NLOS) propagation, thus in a harsh multipath propagation environment. The WiMAX specification proposes 256 orthogonal frequency division multiplex (OFDM) approach to cope with expected channel impairments. Among all subcarriers only 192 of them...


T he purpose of blending in a petroleum refinery is to mix semi-finished products that have been rectified during various refining processes so as to manufacture a product that meets specification. Traditional blending operations have not been able to avoid the following issues involving property control: • Manual adjustment by the operator cannot control the properties ideally and is liable to cause giveaway (an excess in quality). • A conventional analyzer, typically a knockmeter, requires a large amount of labor and high costs for installation and maintenance. The objectives of the development of this blending optimization system are, first, to employ an optimization calculation in the blend ratio calculation, and further, by structuring an integrated system package including analyzers, to reduce costs and labor drastically for users employing the system (the troublesome testing of system connections, etc.). *1 Systems Business Division *2 CENTUM is a registered trademark of Yokogawa Electric Corporation.
