A question in GATE 2012 Mining Engineering Paper with Solution has been updated:
Statement for Linked Answer Questions 54 and 55:
In a mine between upcast shaft and downcast shaft, two airways are connected in parallel and their resistances are 100 and 120 N
respectively. The resistance of upcast shaft, downcast shaft and the fan drifts are 10, 20 and 5 N
respectively. The fan drift air pressure is 15
.
The rate of airflow through the mine in
is
- 333.33
- 240.35
- 18.26
- 4.16
