Question:
The operating point of a mine fan is
The operating point of a mine fan is
Show Hint
The operating point of a mine fan is determined by the intersection of
\[
\boxed{\text{Fan characteristic curve and mine characteristic curve}.}
\]

- The intersection of fan efficiency versus quantity curve and mine characteristic curve
- The intersection of fan pressure versus quantity curve and mine characteristic curve
- The intersection of fan air power versus quantity curve and mine characteristic curve
- The intersection of fan speed versus quantity curve and mine characteristic curve

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the operating point of a mine fan.
The operating point is the condition where the pressure developed by the fan equals the pressure required by the mine ventilation network.
Step 2: Identify the corresponding curves. This point is obtained at the intersection of the \[ \boxed{\text{Fan pressure--quantity (P--Q) curve}} \] and the \[ \boxed{\text{Mine characteristic curve}.} \] Hence, \[ \boxed{(B)} \] is the correct answer.
Step 2: Identify the corresponding curves. This point is obtained at the intersection of the \[ \boxed{\text{Fan pressure--quantity (P--Q) curve}} \] and the \[ \boxed{\text{Mine characteristic curve}.} \] Hence, \[ \boxed{(B)} \] is the correct answer.
