Pie chart |ಪೈ ಚಾರ್ಟ

Pie chart is circular statistical graphical representation of data, which is divided into sectors of circle to illustrate numerical proportion. here each sector represents data about a given particular category. The sector of circle are constructed in such a way that the area of sector is proportional to the corresponding value of given data and that area intern depends upon angle of sector which interns proportional to the data given.In pie chart the total quantity is distributed over an angle of 360 degree that is 100%.

Since the area of sector is proportional to the corresponding value of components and their ratio will becomes equal.

Let us solve one problem-

In a class there are 90 students from which 20 are interested in science only, 10 are interested in mathematics only, 12 are interested in sports only, 16 are interested in social studies only, 8 are in languages only and remaining interested in cultural activities only. Draw pie chart for given information.

Solution:

1st we will make the table and then we will draw the pie chart after filling of table

1st we will find angle and % correspond to who interested in science

We know,

Here we need to find the center angle of component i.e

Here the value of component means number of students who interested in science i.e 20
Then,

In the same way we will find percentage also. Here we will slightly alter the formula.

Then the table will become

In same way we will perform all the calculation. After filling all the the data finally the table will becomes,

T01- Introduction to Turning on Lathe

What is turning ? Turning is a machining process used to generate cylindrical and conical surface by rotating the work piece and with the help of cutting tool. The machine where the turning process is usually carried on is called as lathe , where a cutting tool is fed against a rotating work-piece. What is the working principle of Lathe? The principle of operation is shown in the figure. Here both the work piece and the tools are rigidly held on the lathe. Then the tool is provided with longitudinal and transverse movement while the work-piece is being rotated at suitable speed. Basically three type of major surface can be produced depending on the movement of the tool, They are as follows:- I. When the tool moves parallel to the axis of rotation of the work piece, a cylindrical surface can be produced. Which is as shown below. II. When the tool moves at an angle to the axis of the work piece, a tapered surface can be produced. Which is as shown below. III. When the tool moves perpe

Jowar (ಜೋಳ)

It is flowering plant belongs to grass family Poaceae . It is also known as Sorghum, which is cultivated extensively in India and other country. Earlier Jowar was used in food made for animals but now people have started incorporating it in their diet due to its incredible health benefits. Now a day all bakery and homemade dishes make uses of all-purpose flour/Maida which is not good at all for health. A healthy alternative to all-purpose flour is jowar. This is rich in protein, Potassium, Calcium and other minerals. Since the jowar is gluten free, it plays a critical role in cellular function and repair. The rich quantity of Potassium & Phosphorus helps lower cholesterol and mange High B.P. The grain is incredibly rich in fiber and hence should be part of diet. Nutrition facts per 100 Gram: Total fat-3.5 g Saturated fat-0.6 g Total carbohydrate- 72 g Dietary fiber-6.7 g Sugar-2.5 g Protein-11 g Calcium-13 mg Iron-3.36 mg Potassium-363 mg Sodium-2 mg Benefits of jowar i) High fi

H09- Internal gear pump

A gear pump consist of two meshing gear. One of the gear is connected to a driving shaft known as D river gear which drives 2nd gear called D riven OR Idler gear . These gear are enclosed inside the housing. These pumps are particularly used to transfer viscous fluid. Constructional feature: In this type of the pump the meshing of the teeth takes place internally and hence the name internal gear pump.it consist of external gear which meshes with gear which contains internal gear as shown in figure. The pumping chamber is formed between the gear teeth. A crescent seal is machined into the space between the inlet and outlet OR meshing and unmeshing region of the gear where the clearance between the internal gear( annular gear) and external gear is maximum. Thus the crescent seal separates both inlet and outlet and it will not allow the fluid to return the inlet. Working : Low pressure oil from the inlet port is converted into high pressure oil at outlet as follows.
