Estimating Highway Maintenance Work Estimating amounts of materials, work done, size of crews, or number of trucks needed for road maintenance requires the skill of working with NUMBERS and MEASUREMENTS . By using addition, subtraction, multiplication, division and some basic rules, you can do some figuring ahead of time and make your crews look better. People feel better about themselves when they’re doing a good job, their friends do too, and so does the motoring public. NUMBERS play an important part in the everyday affairs of everybody. -
Water System Operator's Guide
MATH REVIEW For a rectangular tank: Most math problems a water treatment plant To find the capacity of a rectangular or square operator solves requires plugging numbers into tank: formulas and calculating the answer. When working with formulas, here are some simple Multiply length (L) by width (W) to get area (A). rules to follow. • Work from left to right. Multiply area by height (H) to get volume (V). • Do anything in parenthesis first. Multiply volume by 7.48 gallons per cubic foot to get capacity (C). • Do multiplication and division in the numerator (above the line) and in the A = L x W denominator (below the line), then do V = A x H addition and subtraction in the numerator C = V x 7.48 and denominator. • Divide the numerator by the denominator Find the capacity of a rectangular tank 15 feet (ft) last. long, 12 ft wide, and 10 ft high: Volume A = 15 ft x 12 ft = 180 square feet (ft2) The volume of a tank in cubic feet is equal to V = 180 ft2 x 10 ft = 1,800 cubic feet (ft3) the tank area multiplied by the tank height. The C = 1,800 ft3 x 7.48 gal/ft3 =13,464 gal capacity in gallons is equal to the volume in cubic feet multiplied by 7.48 gallons per cubic foot. For a circular tank: Area (A) = (3.14) x diameter squared (D2) / divided by 4 Volume (V) = A x H Capacity (C) = V x 7.48 gal/ft3 A = [ x (D2)/4] V = A x H C = V x 7.48 49 Find the capacity of a circular tank with a For an oval tank: diameter of 15 ft and a height of 12 ft: To find the gallons in an oval tank: A = [3.14 x (15 ft2)/4] = 177 ft2 Multiply the height by width by (3.14) divided by 4 to get the area of the oval. -

CARPETING Jonathan is carpeting his bedroom. It is 15 feet long and 12 feet wide. While shopping, he notices glencoe.com carpet is sold in square yards. 12 ft 1. How many feet are in one yard? 3 2. How many yards long is the room? 5 15 ft 3. How many yards wide is the room? 4 4. What is the area of the room in square yards? 20 yd2 You can use the formula for the area of a square,$" A = s2, to find the number of square feet in one square yard. Convert Area Measurements Convert one square yard to square feet. A square yard is a square with a side length of one yard. You know that one yard is equal to three feet. So, one square yard is a square with side length three feet. 1 yd A = s2 Write the formula. 1 ft 1 ft 1 ft 2 A = 3 Replace s with 3. 1 ft A = 9 Simplify. 1 yd 1 ft So, one square yard is equal to 9 square feet. 1 ft Convert one square meter to square centimeters. A square meter is a square with a side length of oneC09-014A-891643 meter. You know that one meter is equal to 100 centimeters. So, one square meter is a square with side length 100 centimeters. A = s2 Write the formula. -

Explanation of Flow Rate
Explanation of Flow Rate Rate: Rate problems are any measured amount over another variable (a ratio). An example would be distance over time like miles per hour. It could be unit price of an item or a production rate. Rate problems are very common in all standardized math tests. Examples: $3 Unit Rate $3 per gallon is 1 gallon 80 miles 60 minutes 80 miles in 90 minutes is 90 minutes x 1 hour =53.3mph Flow rate is an amount of fluid traveling over time. It is a key concept when working with any fluids from medical to hydraulics. Here we are primarily looking at water flow rates. Flow rate is the amount of water (volume) over time. The amount of water moving through the system can be measured in one of three different units. They are gpm (gallons per minute), mgd (millions of gallons per day), and cfs (cubic feet per second). Example: Convert cfs to gallons per minute: 90 cf 7.5 gallons 60 seconds 90 cubic feet per second is sec x 1 cf X 1 minute =40,500 gallons per minute Instructional video on how to calculate flow rate The conversions are listed below. 7.5 gallons = 1 cubic foot 5280 feet = 1 mile 640 acres = 1 square mile 43560 square feet = 1 acre mgd x 700 = gpm cfs x 449 = gpm Example: A pipeline has a carrying capacity of 3 cfs. How many gpm can it handle? 3 cubic ft. 7.5 gallons 60 seconds 1350 gallons Solution: 1 second x 1 cubic foot x 1 minute = : minute Example: If the dimensions of California are approximately 220 miles wide and 740 miles long, what is the surface area in square miles of our state? Solution: SA = 220 miles x 740 miles = 162,800 square miles Example: If we had a state average annual rainfall of 30 inches, how many acre feet of water would that be? 640 acres 1 ft. -
Basic Information About Cubic Scaling
BASIC INFORMATION ABOUT CUBIC SCALING The primary reason for scaling logs is to establish log value, which is then used as a basis for payment. The most important secondary reason for scaling logs is to predict the quantity of end- products that can be recovered from a log. The major end-product produced from logs is lumber. Lumber is manufactured in a variety of sizes, each size having different applications. Besides lumber, additional end-products are produced from logs, each also having different applications. Veneer, chips, and sawdust are all used in the manufacture of many engineered lumber products plywood, oriented strand board (OSB), high-density particle board, etc. The predominant log scale rule used today Scribner decimal “C” does a pretty good job in reflecting log value, but has inherent limitations. Scribner predicts volume in board feet, based on boards that are one-inch thick, within a cylinder equal to the small-end log diameter. Other procedures become necessary to determine product recovery not predicted by the design of the Scribner decimal “C” log rule. Cubic scale does not predict a specific product volume. Instead of reflecting board feet, cubic scale reflects log volume in cubic measure. Since it doesn’t reflect a specific end-product, a cubic scale rule design can reflect volume differences due to varying log sizes and taper. The design of a cubic scale rule is based on a formula. The Smalian cubic log rule is one of the most common cubic measurement systems, probably because it is easy to use. As applied by the United States Forest Service in their Cubic Scaling Handbook, it reflects the volume of a log in cubic feet. -

Tennessee State Library and Archives
Tennessee Archives Management Advisory 1999 ARCHIVAL CONTAINERS: TABLES OF CUBIC-FOOT EQUIVALENTS FOR CONTAINERS, SHELVING, AND CABINETRY COMMONLY FOUND IN ARCHIVES Introduction. The bulk or volume of material in archives is an important element of planning and reporting the amount of material that is accountable, usable, stored for preservation, and retrieved for use. It is also important to planning the construction of new facilities. Converting common containers to useful measures for planning and reporting is necessary to archives management. This handbook offers some close approximations to practical conversion factors. Metric versus Traditional Measures. Traditional English measures are used throughout instead of metric measures.1 Linear Shelf Feet versus Cubic Feet. When not measuring their holdings in numbers of unique titles, librarians conventionally measure their holdings in linear feet of standard-width shelving occupied by their books. For archivists, the “reportable unit” of holdings is usually the record group or “collection”. Archivists sometimes also use linear feet for reporting the amount of shelving used or needed, but they more commonly use cubic feet because of the variable volume of archival containers and the variable size of shelving required. A standard rule of thumb is to make a one-to-one equivalent between cubic feet and linear shelf feet to calculate the linear footage of standard-size shelving that is required to hold any body of records. However, this works well for only one type of container, the standard “records center carton”, which contains one cubic foot of papers. Though it works tolerably well for the legal-size standard document cases (often called by the trade name of “Hollinger Box”), it does not do so well for letter-size cases, half-boxes, and flat cases, and not at all for magnetic tape boxes or motion-picture film cans. -
