Problem #2: Air at 100 kPa and 300 K is drawn into a tube having an inside diameter of 2.5 cm by a vacuum blower. A static pressure tap in the flow tube is connected to an open dish of water placed 10 cm below the static pressure tap with a second piece of tubing (see below). Assuming the airflow to be ideal, determine the maximum flow rate (Liters/min or LPM*) allowable before water would be drawn into the blower inlet. [note: the author observed this situation in prior industrial experience when two engineering design teams were disputing the functionality of a vacuum blower system and attempting to prove their case with this experiment].
