Question Statement:

A grain auger conveyor utilizes a screw with lead L = 150 mm. If the auger rotates at 200 RPM, what is the theoretical linear axial conveyance velocity of grain along the trough (assuming 100% volumetric efficiency and no slippage)?

Options:

  • (A) 30 m/min (0.5 m/s)
  • (B) 15 m/min
  • (C) 60 m/min
  • (D) 1.33 m/min

Answer Key:

A

Step-by-Step Solution & Explanation

Linear velocity v = L * N = 0.150 m * 200 rev/min = 30 m/min = 0.5 m/s.
