An open tubular column used for gas chromatography had an inside diameter of 0.25 mm. A volumetric flow rate of 0.78 mL/min was used. What is the linear flow velocity in cm/s at the column outlet? 1 cm = 1 mL F = uoA = UoTr?

With the unique velocity profile of each liquid, determine the distance from the leading center to that point of the profile where the velocity is 3.2 m/s.

erical pa for steady FLUID Flow Q: Yotameter with float shape type "B" (see figure below) has tube of 0.3 m long. the internal diameter of the Yota meter is 25 mm at the P and 20mm at the bottom the climmeter of the float is 20mm its elensity is Bl00g/2 and its volume is 5.0 cm² what is the mass flow rate of water (at 25 ℃) When the float Position 0-2 m from the bottom of the tube ? is

A ventilation opening in a room is 2 feet by 3 feet.  Air flow out of the opening is measured at 75 feet per minute.  Calculate the CFM rate.
