A rotameter is a device that measures flow of liquid and gases. When measuring liquid phase flows, 2.5 inches represent 60 liters per minute of liquid. With gas measurements the rotameter moves 50% of the movement he moves with the liquid phase. How many liters of gas passed through the rotameter if it measured 4 inches?
Select:
A) 176
B) 192
C) 202
D) 218
E) 284
In case of liquid- 2.5 inches represents 60 lit/min.   In case of gas- 50% of 2.5 inches represents 60 lit/min   1.25 inches represents 60 lit /min   4 inches will represent   60*4/1.25=
