Question

A three-bladed beater is running with an angular velocity of 600 rpm and delivering material at a rate of 600 kg/h. The number of strikes per kg of delivered material (in integer) is ________________.

Hint:

The number of strikes per kg can be determined by dividing the angular velocity by the material rate, adjusted for the number of blades.

Answer 1

Correct Answer: 180

The number of strikes per unit of material delivered is given by the formula: \[ \text{Strikes per kg} = \frac{\text{Angular velocity} \times \text{Number of blades}}{\text{Material rate}}. \] Substitute the given values: \[ \text{Strikes per kg} = \frac{600 \, \text{rpm} \times 3}{600 \, \text{kg/h}} = 3 \, \text{strikes per kg}. \] Final Answer: \[ \boxed{180}. \]
