DESIGN OF MULTI NOZZLE BATTERY SPRAYER
The tank is of Hollow square bar with a size of 400 * 400 mm.
The capacity of the Tank = 16 litre
BATTERY SELECTION
Specification of Battery
Charging Instruction
• Temperature = 25
• Charging time = 3 hr

9. COST ESTIMATION
S.NO COMPONENT NAME PRICE IN Rs.
1. Tank 600
2. Nozzle 180
3. Pipe 100
4. Hose 120
5. Battery 600
6. Pump 450
7. Filter 100
8. Bolts and Nuts 25
9. Welding and Mechanic work 400
10. Others 100
Total 2675

10. Spraying Done By Manual Process :
Amount paid to the labor for one day = Rs. 500 per labor
Total number of labor required in general to spray 1 Ac = 4
Total amount paid to the labour = 4*500 = Rs. 2000/ day / acre
Therefore, Total expenditure in one day is = Rs. 2000
Spraying Done By Battery Machine:
Consumption of electricity required for 1 acre = 6 units
Cost of electricity per unit = Rs. 7
Total cost of petrol for 1 acre farm for a day = 6*7 = Rs. 42
Amount paid to the labor = Rs. 500 per day
Total expenditure = Total cost of electricity + Amount paid to the labor
= Rs. 42 + Rs. 500 + Rs. 30
= Rs. 572 ~ Rs. 580
Amount saved by using the automatic removal machine = Rs. 2000 – Rs. 580 = Rs. 1420 / day / acre
Spraying done by Pneumatic Sprayers
Amount paid for labor for spraying 1 acre = Rs. 500
Amount spent for spraying the 1 acre by = manpower + maintenance = 0 + 100 = Rs. 100
Amount saved by Automatic spraying machine = Rs. 500 – Rs. 100
= Rs. 400
