A 6 by 100ml used drills is to plant 10kg of maize per hectare.if the diameter of the drive wheel is 2m. calculate (1) the width of the seed drill.(2) the length of travel necessary for the drill to cover 1 hectare (3) the number of wheel revolution to cover 1 hectare.(4) the amount of seed grain each to be discharged to plant 1 hectare?
To answer each of these questions, we need to use the given information and apply some calculations. Let's go through each question step by step:
1. To calculate the width of the seed drill, we need to know the amount of maize planted per hectare and the number of drills. Since we have 10kg of maize per hectare and 6 drills, we need to divide the total amount of maize by the number of drills:
Width of the seed drill = Total amount of maize / Number of drills
Width of the seed drill = 10kg / 6 drills
2. To calculate the length of travel necessary for the drill to cover 1 hectare, we need to know the width of the seed drill and the area of 1 hectare. The area of 1 hectare is 10,000 square meters. The length of travel can be calculated using the formula:
Length of travel = Area of 1 hectare / Width of the seed drill
Length of travel = 10,000 square meters / Width of the seed drill
3. To calculate the number of wheel revolutions to cover 1 hectare, we need to know the circumference of the drive wheel. The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Since the diameter of the drive wheel is given as 2m, we can calculate the radius by dividing the diameter by 2. Then, we can calculate the circumference using the formula mentioned above. Once we have the circumference, we can calculate the number of wheel revolutions using the length of travel. The formula is:
Number of wheel revolutions = Length of travel / Circumference
4. To calculate the amount of seed grain to be discharged to plant 1 hectare, we need to know the amount of maize to be planted and the number of wheel revolutions. We can calculate this by dividing the amount of maize by the number of wheel revolutions:
Amount of seed grain to be discharged = Total amount of maize / Number of wheel revolutions
Now you can plug in the values and perform the calculations to find the answers to each of the questions.
