Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

carcass can of two major types:
1. Fabric ply type 2. Steel cord type
CONVEYOR BELT CONSTRUCTIONAL DETAILS.
28. B) Skims:
The rubber, PVC or urethane between the plies is called as skim. Skims are important contributors to internal
belt adhesions, impact resistance and play a significant role in determining the belt load support and trough
ability. Improper skims can give reverse effect too. It can lead to ply separation failure.
C) Covers:
They are used in conveyor belt construction to protect the conveyor belt carcass and also to extend its
service life. Therefore, the top cover normally will be greater in thickness than the bottom cover to take care
of wear of conveying side of belt.
Its desirable properties such as:
1) Textures
2) Clean ability
3) A specific co-efficient of friction
4) A specific color
5) Cut resistance.
6) Enhanced impact resistance.
7) Hardness. 8) Fire, oil and chemical resistance.

40. BELT CONVEYORS
A belt conveyor consists of an endless belt of a resilient material connected between two pulleys
and moved by rotating one of the pulleys through a drive unit gearbox, which is connected to an
electric motor. The driving pulley end is called as head end, and the pulley is called as head pulley.
Conversely, the other pulley is at the tail end and is referred to as the tail pulley.
41.
42. A)HEAD PULLEY: - Normally the discharge end of the conveyor where the material is transferred to another
conveyor is called as the Head end and the pulley in this end is called the head pulley.
B) TAIL PULLEY: - The pulley which is situated in the receiving end of the conveyor is called as tail pulley.
Sometimes Screw take-up will be situated in this pulley.
GENERAL ARRANGEMENTS OF BELT CONVEYOR
43. E) IDLERS: - The needs for Idlers are to give proper support to conveyor and also to the Material
to conveyor. An endless conveyor belt in a conveyor structure is dragged from the tail pulley
where material is loaded onto the conveyor, to the head pulley or drive pulley where the material
is discharged. Between a conveyor' tail and head pulleys, whether the distance is a number of
kilometers or merely a few meters, the carrying and return strand belting is supported on idler
sets.
a) TROUGHING IDLER
b) TRAINING IDLER
c) IMPACT IDLER
d) RETURN IDLER
e) GUIDE IDLER
The most commonly used troughing idler has three rolls of equal length with inclined rolls usually
of troughing angles of 20 deg. 35 deg & 45 deg. 20 deg are standard in most application.
44. C) SNUB PULLEY: - Snub pulleys are incorporated into the design of a conveyor in order to increase the angle
of wrap of the belt on the drive pulley.
D) SCRAPERS: - The function of the Conveyor Belt is to carry material and during this process material sticks
to the Belt for which Belt Scrapers are used to clean the Belt.
47. G) TAKE UP: -Take up devices, the name from the fact that it takes up changes in belt length. In taking up
length they maintain tension. Often the critical point lies immediately following the drive since it is
necessary to maintain tensions at the point to prevent slippage on the drive pulley.
F) Manual (Screw type):- The screw type (manual type) providing enough movement to establish initial
tension in the belt and to provide periodic readjustment as the belt stretches.
G) Gravity (VGTU) - Vertical Gravity Take UpAn automatic take-up (counter weight) must provide sufficient
travel to handle any elastic length changes due to load variation or temperature changes and inelastic
changes likely to occur between refastening and replacing.
H) SKIRT BOARD: - The chute having delivered material the succeeding belt; has no further control of the
material. To control on loading turbulence, the skirt board are necessary.
TYPES OF TAKE UP
48. I) CHUTES: - Chutes are generally of two types feed chute and discharge chute; feed chute are used for
feeding the materials in the belt and it is situated near the tail pulley and discharge chute is used for
discharge the materials and it is situated near the head pulley.
49. J)Lagging:
Enhances coefficient of friction between belt and the drum/pulley to
reduce
required equivalent tension for belt operation
– Rubber lagged pulley
• Plain rubber sheet
• Diamond sheet
• Herringbone pattern
– Ceramic lagged pulley (very high wear
life) Ceramic shapes embedded in
rubber matrix
• Straight ceramic bars
• Custom built ceramic shape
• Small ceramic squares/honeycomb or other shapes

1. Open belt drive
2. Crossed belt drive
3. Quarter turn belt drive
4. Compound belt drive
5. Belt drive with idler pulleys
6. Stepped or cone pulley drive
7. Fast and loose pulley drive
53. QUESTION: If drive diameter is 800 mm and tail diameter
is also 800 mm and both pulley is separated
by 6 meter . Find total length of belt for this system?

𝝅d1N1= 𝝅𝐝𝟐𝐍𝟐 , 𝐝𝟏 = 𝐝𝐢𝐚, 𝐍𝟏 = 𝐑. 𝐏. 𝐌 of 1st pulley.
N2/N1=d1/d2
N2/N1= d1+t/d2+t ,where t is thickness of belt
In case of compound belt drive velocity ration
is given by
N4/N1=(d1xd3)/(d2xd4)
Speed of last driven/Speed of first driver=
Product of diameters of drivers/Product diameters of driven
55. Length of Open Belt Drive:
Length of belt = 𝜋(r1+r2)+2x + (r1-r2)^2 /x
Work done per sec =(T1-T2)Xv N-m/s
Power transmitted = (T1-T2)Xv Watt (1N-m/s= 1W)
56. Ratio of driving tensions of flat belts:
T1= Tension in the belt on the tight side.
T2= Tension in the belt on the slack side.
Loge (T1/T2)= µ.Ө
T1/T2= e^µ.Ө
2.3 log10 (T1/T2) = µ.Ө
57. When thickness of the belt is known:
L = ((D*D)-(C*C)) / (15.3*t)
L = Length; D = Outside Diameter (inches); C = Inside
Diameter (inches); t = belt thickness (inches)
When wraps are known:
L = ((D+C)*3.14*n) / 24

58. Question :Two pulleys ,one 450 mm diameter
and the other 200 mm diameter on parallel
shaft 1.95 m apart are connected by a crossed
belt .Find the length of the belt required and the
angle of contact belt and each pulley.
What power can be transmitted by the belt
when the larger pulley rotates at 200 rev/min ,if
the maximum permissible tension in the belt is 1
KN , and the coefficient of friction between belt
and pulley is 0.25 ?
59. Angle of contact between the belt and each
pulley
Sin alfa= r1+r2/x=.225+.1/1.95=.1667
Alfa=9.6
Theta=180 degree +2 alfa= 180+ 2x9.6=199.2 degree
60. Power Transmitted:
2.3 log(T1/T2)= MuX THETA
Log(T1/T2)= .8693/2.3=.378
ANTILOG Of .378= 2.378
T2= T1/2.387= 1000/2.387= 419 N
We know velocity of belt v= PIEXd1xN1/60
= piex.45x200/60= 4.713 m/s
Power transmitted = P= (T1-T2)XV=(1000-419)X4.713=2738W
= 2.738 kW
61. Ans:
Length of belt= 4.974 m
Angle of contact =199.2 degree
T2=419 N
V= 4.713 m/s
P=2.738 kW
62. Conveyor Belts used can be categorised into Bucket Conveyor, Chevron Conveyor &
Troughing Conveyor.
Belts can come with features
With Breaker:-Fabric Breaker, Steel Breaker
Without Breaker
With Rip Detection loops
With RFID
Edge Construction
Moulded Edge-Steel Cord(will rust if left open), Fabric belts where Oil & Chemicals can
react with fabric.
In moulded Edge - First damage happens to the edge rubber & saves the internal
construction.ME belts are Costly in comparison to same spec CE fabric belt
Cut Edge- Fabric Belts used in normal operating condition belt. Synthetic fibres used these
days are less susceptible to environmental conditions.
63. Hardness
Usual approach is to check with Shore A durometer. 60-70 Shore A when new,
unused, stored well.
Pulley Diameter
Minimum Pulley Diameter
The smallest pulley diameter that the belt will encounter in the
conveyor system is a primary consideration in selecting the
proper conveyor belt.
It is important that as the belt wraps around that pulley,
under tension, the stress in the belt is below the fatigue limit
of the bond between the belt components.
Due to system limitations, smaller than recommended pulleys
may be used. This will affect the service life of the belt and will
result in more frequent splice replacements.
64. When transitions are shorter than
suggested minimum, belt damage
can occur.
At the high tension area, such as
the head pulley or tripper discharge,
excessive edge tensions will cause
adhesions to break along the edge of
the belt, and can also rupture the
carcass in severe cases.
At a low tension terminal, such as the
tail, short transitions will cause a
belt to buckle at the bottom of the
trough, resulting in splice failure and
cover adhesion breakdown in the
center of the belt.
