4.1. Optimal Conditions for Scraper Use

Try these first

1. 1.

   What is the production output when using 5 scrapers?

   Hint

   Refer to the section discussing the number of scrapers.

2. 2.

   Define a bank cubic meter.

   Hint

   Look at the glossary terms provided.

3. 3.

   What is the production output when using 5 scrapers?

   • 636.89 BCM/Hr
   • 723.36 BCM/Hr
   • 500 BCM/Hr

   Hint

   Review the section discussing the productivity of 5 scrapers.

4. 4.

   True or False: Having more scrapers than needed can make them go idle.

   • True
   • False

   Hint

   Think about how the excess scrapers affect operation flow.

5. 5.

   Calculate the total production for a project requiring 60,000 bank cubic meters if using 5 scrapers continuously at full efficiency.

   Hint

   Use the production output to determine the time needed.

6. 6.

   Consider a project where you switch from 5 to 6 scrapers midway. Analyze how this change impacts both productivity and costs over a month.

   Hint

   Understand how the switch changes both outputs and financial implications.
