Construction ManagementConstruction EquipmentMEDIUM
Choose the correct answer
A
5.0 m³/hr
B
6.25 m³/hr
C
8.33 m³/hr
D
10.0 m³/hr
Correct Answer
C. 8.33 m³/hr
Why is this the answer?
Productive cycles/hr = 50 min ÷ 3 min = 16.67 cycles. Output = 16.67 × 0.5 m³ = 8.33 m³/hr. Efficiency factor accounts for changeover, setup and minor delays; a 50/60 ratio (83%) is standard for batching plants.
