Find the maximum area of the rectangular feild which is surrounded by a 100 m rope?

 Perimeter of the rectangle = 2 (L+B)

as per question 2 (L+B) = 100

                                L+B = 50

Area of the rectangle = L X B

we need to find the area of the rectangle so the maximum values of L and B must be 25, 25+25 =50 

so The maximum value is 25 X 25 = 625

                                    (Or)

L + B = 50 

B = 50 - L

Area = A = L X B

A = L X (50 - L)

    = 50 L - L^2

First derivative W.R.T  'L' gives 

dA/dL = 50 - 2L 

the value will be max when dA/dL will be minimum (or) zero

0 = 50-2L

L= 25

then B = 50 -L => B = 25

Polyethylene - PE - Pipes and Pressure classes

HDPE - High density polyethylene - is highly used material for water pipes. These pipes are

· Flexible

· Long Life

· Chemical Resistant

· Less weight

· Resistant to Sunlight

· Less friction

· Cheaper in cost

· tough

· ductile

· ability to dampen water shock.

The standard specification of HDPE pipes is Nominal pressure - PN . Polyethylene pipes can be used in-between -40 to 60 C based on operating pressure. Based on the material used they also be classified as PE 32, PE 40, PE 63, PE 80 and PE 100. 

The pressure grades available in market according to European Standards are  

PN 2.5 - i.e., Maximum pressure it can bare is 2.5 bar

PN 4 - Maximum pressure is 4 bar

like that PN 6, PN 10, PN 16 etc., 

For pressure conversions follow this link

Color Codes and Pressure Grades

Generally color codes are given to the pipes to indicate the pressure.

PE Pressure Grade	Color Code
PN 16	Green
PN 10	Blue
PN 6	Red
PN 4	Yellow

PE 32 & PE 40  pipes are used for low pressure piping systems. PE 63 pipes are used for medium pressure piping systems like drinking water connections, Irrigation purposes. PE 80 pipes for natural gas distribution and drinking water pipes up to 16 bar pressure. PE for high pressure distribution systems.

Color Codes and Materials Classifications

In some special cases pipes are given some colors to identify where we can use these pipes. 

· In general complete black colored pipes for industrial applications

· complete blue (or) black with blue stripes, for potable water applications

· complete yellow (or) black with yellow stripes, for gas conduits

Note: These colors may change based on countries.
