- Delivery Rate of Agricultural Dusters:
- Standard Specifications (IS 5133 / IS 8758): For manually operated rotary and knapsack powder dusters, the maximum delivery setting must ensure uniform, rapid chemical application across target crop canopies.
- Minimum Output: The delivery rate at the maximum discharge opening setting shall not be less than $150\text{ g/min}$ ($150\text{ g}\cdot\text{min}^{-1}$) when operating at rated cranking speed (approx. 30–35 rpm of crank handle yielding 2500–3000 rpm of impeller).
- Conclusion: 150 g.min$^{-1}$ (Option 2).
