Conclusion
the basic measurement of a rainfall is of how much rain falls in a specified period of time the depth of rain accumulating on a level surface without cooking in running away or evaporating then depth is usually major in mm rainfall is measured by catching water over a given time in a suitable jar usually with a funnel
smokeless chulha
Aim
to compare the smokeless chulha with traditional chulha
Requirements smokeless chulha traditional chulha until for cooking wood for burning 250 grams rice packets stopwatch
procedure
overall objective is to compare both smokeless chulha with traditional chulha on the following parameters
Cooking rice of 250 grams simultaneously all bath smokeless chulha and traditional chulha
put 250 grams of rice in a both the until equal quantity of water in both the until major equal quantity of firewood for both stoves
start cooking rice from the stop watch not the time
monitor which store separately after cooking not the following
time required for cooking.
quantity of wood burnt.
quality of the rice cooked
quantity of rice cooked | time consume for cooking | quantity of wood burnt for cooking | quality of rice cooked | |
traditional Stove | ||||
smokeless stove |
from the above observation table derive the conclusion on the fullness of the smokeless chulha over the traditional chulha
material needed for construction of smokeless chulha
Breaks off mud made out of
clay, sand, bhoosa, paddy husk, cow dung
chimney made of metal or asbestos cement pipe
Biogas
Aim
to use biogas plant
requirement
fresh dunk water metre tape calculator
Procedure
mix a fresh dog and water with right proposition in the inlet tank as per capacity of biogas plant
continue the above procedure in summer winter and rainy season for minimum 7 days regularly
observe the production of gas during feed period
The get value should be open only when the gas has to be it actually used this will avoid the un necessary westage of gas
students should be given demonstration and assignment to carry out daily feeding weekly and monthly maintenance
daily maintenance add the recomoned quantity of row material used proper salary mixture, yuddh clean feedstock free from soil and straws
weekly maintenance
Monthly maintenance
Check gate value gas outlet pipe and and gas pipe fitting for leakage
check the pipe of moisture trap for any possible leakage
annual maintenance
Take for gas and water leakage for pipe and application open the game value and remove all the gas from the plant after the the level of salary in the outlet pipe chamber
Five years maintenance
Empty the plant clean the the sludge and inorganic material from the bottom of plant repeat the gas storage chamber with black enumal plant recharge the plant with fresh slary
soak pit
Aim
to make a soak pit
requirement
Burnt bricks, stone bricks pit digging instrument pebbles
procedure
Look out for a place where used water is accumulated dig a pit of 1 m into 1 m into 1 m dimension film bottom 1by3 with coconut sides tone middle one by three with coconut size bricks fill top 1 by 3 with lime size pebbles for burnt bricks discharge the used water into the soak pit
observation
a sludge soak pit is the one in which the drain age from the house drain is directly discharge the water in the accumulated sewage is soaked by adjoining previous soil while the sludge is digested in the pit these teeth are also useful around the hand pump and cloth washing area this reduce the water closing and prevent breeding of mosquitoes and flies
conclusion
seat tribe of size 1 m into 1 m into 1 m or 25* 25* 25 mm closing of soch pit periodically the sit can be removed from the silt .
level tube
Aim
Tula the use of level tube
requirement
level tube water chalk lime
Procedure
fill the level tube with water with proper care in sure no air bubbles remain in the tube proper way of filling to is to put one and in water and suck water at another end
take the level tube and put one end at one corner of the window and take another corner to other end of window check if window is properly level or not
If new construction is going on at nearby site visit it and observe how Manson check the level tube while fixing the bricks
while doing a brick work in workshop used level tube
observation.
determine difference in height of any two point on the slope using level tube and staff the difference between spots should not exceed to two cm
weak and pressure Stove
Aim
to learn the maintenance of kerosene week and pressure Stove
requirement
caustic soda ,scrubber,old tooth brush , duster detergent powder
procedure
dust and wipe of the spilled food material on the stove. clean the surface with warm soap solution wipe off the soap solution from the surface with the help of a wet duster .trim and clean the weaks and make them uniform in size .dry it under the sunlight learn to use pressure stove and weak stove
functioning of pressure Store
tank ,pump ,burner
tank
tank is made of metal.it has knob to fill up oil similarly it has key to release pressure there is thin tube from bottom of the tank going up to the burner
pump
there is small pump fitted to the tank the pump has rod fit with rubber washer when rod Is a pulledbehind the rubber washer shrink due to outside air pressure allowing air to inside the tank when rod is pushed inside the rubber washer get expanded pushing the air inside the tank
burner
PLANE TABLE SURVEY
Feb 10, 2022 | Uncategorized
AIM: Plane table survey
Requirements: measuring tape, plane table setup, tripod, staff
Procedure: 1.select a area to be surveyed
2. set the tripod and fix the place taken on it
3. Check the level of the the setup using spirit level
4. set on the table in the middle of it a drawing paper and stand with pens
5. when the centre of the paper with a pen
6. at the end points of the plot hold a star
7. using the reactor scale adjust the angle of it such that when viewed from behind the slot the staff should be seen at the centre of the wire or string
8. market with a line
9. take a tape and measure the distance between the plane table and place where the staff is held
10. once the reading is complete you will have a roughly generated map of of the plot
11. as it is easier to get the area of the plot using the triangle method
12. cut the plot area in such a way that you will get triangles of which you would know the length and height
13. then using the formula ½*l*h get the area of the triangles and add them up to get the area of the plot
DUMPY LEVE
Feb 12, 2022 | Uncategorized
AIM: Check and note down the control lights using dumpy level
Requirements: dumpy level setup, area to be controlled
Procedure: 1. fix the tripod on a surface
2. secondly Mount telescope on the tripod and check the level of the tripod
3. check the level on the tripod there in a small circular Box with a bubble inside it should be at the centre of the
4. then set the level of the telescope by putting the IPS in the centre of one of the two spinners or screws
5. spin both the screws at the same time at the inward or outward
6. when the level gets corrected then spend the telescope in 90 degree in short in between the next two screws
7. now adjust the third screw and check the level
8. if the level is correct then spend the telescope now start taking the reading
9. set the staff on the surface roughly 10 metres from the dumpy telescope
10. the reading of the staff seen through the telescope and men down upper middle and lower readings
11. next turn the telescope to one side and more the staff as well
12. then measure the distance between the telescope and the staff distance using measuring tape
13. move the staff to one side and adjust the staff height such that middle is the same on that of the last
14. note down the upper and lower measure distance again and measure it with a measuring tape
HOW SOLAR COOKER WORKS
Feb 9, 2022 | Uncategorized
AIM: To learn how Solar cooker works
Requirements: solar cooker stand set up for 16 something to cook
Procedure: 1/ set up the Solar Cookeer in the sun The mirror facing at the sun
2. it should be reflecting most of the sunlight at the glass kept on the base of the solar cooker
3. put the rice or eggs in the box that is provided with the solar cooker
4. Set the set up where we can get maximum sunlight
Info: the solar radiation get concentrated due to Mirror into the box and gets trapped inside as a result the box itself and food gets cut glass is it is excellent and blocking IR radiation from getting out
