A bulldozer's production curve indicates 120 loose m³/hour based on ideal conditions. Due to clay soil with density at 1800 kg/m³, the operator is of average skill, and visibility is low. Calculate the adjusted productivity.
💡 Hint: Multiply the original curve value by the product of the correction factors.
If operating costs rise by 20% in your project due to unforeseen expenses, recalculate the unit cost if original operating cost was 2000 rupees and original productivity was maintained at an estimated 60 bank m³/hour.
💡 Hint: First adjust costs, then divide by productivity.
