And while accountants are well - trained to identify and correct accounting errors, spreadsheets bring the danger of many other types of errors. That's a scary statistic, especially when one considers that decisions involving thousands or even millions of dollars are often based on spreadsheets. Decisions based on bad information can be hazardous to an organization's bottom line.

The ultimate goal is to have a spreadsheet that produces accurate results, but as worksheets grow in size and complexity, ensuring accuracy becomes more difficult. Making even one small change in a spreadsheet may cause a ripple effect with unexpected consequences. What can a CPA do? This article walks you through different methods and built - in tools that can be used to audit and debug Excel spreadsheets.

The instructions below refer to Excel but also work, with some tweaks, for Excel When initially opening a spreadsheet, first obtain a quick overall understanding of the spreadsheet, its parts, and the interaction between formulas and values.

To see this in action, open the example spreadsheet. When you open the spreadsheet, a circular references warning pops up. Ignore this warning for now. The spreadsheet contains student scores in various categories, which are then weighted to get an overall weighted score for the class.

Examine how it is put together. Because certain areas of this spreadsheet have been named, the name appears over those sections see "Overall View of the Spreadsheet Layout". Note where the formulas are and that there are inconsistencies in the formulas' sizes. In fact, as you zoom in on some of those inconsistencies, you see that they contain hard - coded values rather than formulas. For example, StudentMM is always going to get At some point, that cell formula was overwritten.

In this case, if you copy the formula in the cell below it into cell BB42, you will get the correct score. Knowing where the formulas are and what they are supposed to do is the first step. Syntax errors are the easiest to find because the spreadsheet expresses them in bold.Email preferred method of contact.

Description A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy the dam. Except during flood periods, water does not normally flow over a spillway.

In contrast, an intake is a structure used to release water on a regular basis for water supply, hydroelectricity generation, etc. Floodgates and fuse plugs may be designed into spillways to regulate water flow and dam height. Other uses of the term "spillway" include bypasses of dams or outlets of a channels used during highwater, and outlet channels carved through natural dams such as moraines.

Energy dissipation As water passes over a spillway and down the chute, potential energy converts into increasing kinetic energy. Failure to dissipate the water's energy can lead to scouring and erosion at the dam's toe base.

This can cause spillway damage and undermine the dam's stability. The energy can be dissipated by addressing one or more parts of a spillway's design. Flip bucket - Second, at the base of a spillway, a flip bucket can create a hydraulic jump and deflect water upwards. Ski jump - A ski jump can also direct water horizontally and eventually down into a plunge pool or two ski jumps can direct their water discharges to collide with one another. Stilling basin - Third, a stilling basin at the terminus of a spillway serves to further dissipate energy and prevent erosion.

They are usually filled with a relatively shallow depth of water and sometimes lined with concrete. A number of velocity-reducing components can be incorporated into the their design to include chute blocks, baffle blocks, wing walls, surface boils or an end sill.

These provide a platform for organizing data and performing the single pipeline calculations for pipeline friction loss. However, in order to sustain a competitive advantage in today's marketplace, it is critical that you consider new technology that provides a total system view of the piping system.

This article investigates features which improve your total system view including visualization, calculations, communications, and access. Fluid Flow Software vs. Spreadsheets provide a platform for organizing data and performing the single pipeline calculations for pipeline friction loss.

If done correctly, spreadsheets can save time when performing single pipeline headloss calculations. A clear picture can be better obtained by incorporating the following features into a single fluid flow program:. These features, along with a robust network calculation engine, provide a clearer picture of the piping system. Fluid piping systems are made of pumps, tanks, components, controls, and interconnecting pipelines.

A piping schematic drawing shows how the items in the system are connected. These drawings provide a system overview and are used for the life of the plant.

When calculating the pipeline head loss with a spreadsheet program, the names of the individual pipelines and the design data are taken off the CAD drawing and manually entered into the spreadsheet's columns and rows. This provides a satisfactory method to organize data and eliminates the need to reenter the pipeline information each time single pipeline calculations are performed.

However, the spreadsheet's row and column format does little to show how the pipelines are connected into a fluid piping system. For example when entering a pump on the FLO-Sheet, the pump's unique name is entered, along with the elevation and operating characteristics.

After the various piping system objects are placed on the FLO-Sheet, the interconnecting pipelines are drawn and the pipeline data is entered. The data for the pipe material, valves, and process fluids are looked up in engineering data tables; this not only simplifies data entry, but also insures that the data is entered correctly.

Fluid Flow Software vs. Spreadsheets

Notes and call out boxes can be added to the FLO-Sheet to improve the presentation quality of the piping schematic drawing. A typical pipe sizing spreadsheet looks at only a single pipeline, calculating the head loss loss for a given flow rate.

If the piping system consists of multiple pipelines in series, the total system head loss can be calculated using the spreadsheet's sum feature. If the system consists of branching pipelines it is difficult to set up the spreadsheet to calculate the proper flow rate for each branch.

Piping systems consisting of multiple parallel paths are very difficult to setup using a spreadsheet. Separate spreadsheets need to be developed to evaluate pumps and control valves. The program uses the FLO-Sheet drawing to set up the equations needed to calculate the balanced flow rates.Search Box Search for:.

The best design is to build a concrete wall, approx.

My PE says he threw out all of the old concrete design books, and no other references are available or authorized for purchase.

I want some calculations or a free on-line reference so I can show myself that the wall will hold water, resist a bump from a truck, and not overturn, slide or sink.

I will submit it all to my PE for his approval once I am done. I have not had any luck finding my old school books and notes. Any help will be appreciated. One foot high-sounds almost like a curb. You might consider designing it like a curb, with a gutter pan about 18" wide at the surface.

This is so a truck would sit on this when it bumped the wall, and it would be less likely to slide or tip. Is this crude oil, then maybe an asphalt surface is OK. I would have thought you would need either concrete or a geomembrane.
