What does a Nomograph measure?
A Nomograph is a geographical calculating tool that is designed for approximate graphical computation of any function. The Nomograph, also known as a nomogram, contains a set of n scales, one each for all the variables in the equation.

What is nomogram in statistics?
A nomogram has been defined’ as a diagram, representing a formula, in which each variable is represented by one or more graduated lines, and from which the solution of the formula for any given set of values may be read off by means of an index line.
How do you read a nomograph?
A nomograph is defined as a graph, usually containing three parallel scales graduated for different variables so that when a straight line connects values of any two, the related value may be read directly from the third vertical line at the point intersected by the line.
How do you use a nomograph?
The nomograph is very simple to use: Locate capacity at the bottom of the graph, go vertically to the rotating speed, horizontally to TDH, and vertically to the pump specific speed.
What is a nomograph for dogs?
A nomograph is an estimate of the amount of antibody passed to a litter of pups from the mother via her colostrum. While this antibody is at higher levels, it is able to neutralize viruses such as canine parvovirus and canine distemper virus. Because of this neutralization, puppy vaccine can be blocked.
How do you use nomograph for boiling point?
With the aid of a ruler, draw a line from 20 mmHg in the pressure graph (to the right), through 100°C in the middle graph (“boiling point corrected to 760 torr”, this is 1 atm), and where this line intersects the line to the left (“Observed boiling point”), take your reading which should be about 15°C.
What is the advantage of using nomograms for design of masonry structures?
The unique advantage of nomograms is its visualizing of the relationship of involved parameters. This offers the possibility of playing around with new values and different assumptions and of optimizing solutions in an iterative process in line with actual requirements.
Which is the correct definition of a nomogram?
A nomogram (from Greek νόμος nomos, “law” and γραμμή grammē, “line”), also called a nomograph, alignment chart, or abaque, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a mathematical function.
What are the assumptions in the nomograph method?
The nomograph is based on the following assumptions: 1. Depreciation method is the sum of the years-digits. 2. Project economic life is equal to depreciable life ( T ). 3. Construction time is zero, i.e. total investment occurs instantaneously at time zero. 4. There is no salvage value at the end of the project life.
How is the nomograph used in the real world?
The nomograph was developed for the case in which the yearly profits (P) (or the difference between income and costs) are equal through the life of a project. The nomograph is based on the following assumptions: 1. Depreciation method is the sum of the years-digits. 2. Project economic life is equal to depreciable life ( T ). 3.
How is the pressure drop in a nomograph calculated?
The nomograph (Figure 1) is based on a modified version of the Fanning equation. It gives the pressure drop per 100 ft of pipe for liquids flowing through a circular pipe. The basic equation is: Figure 1. Pressure drop in liquid lines for turbulent flow. P 100 = Pressure loss per 100 ft of pipe, psi f = Friction factor (4 × f ′ in Fanning equation)
