- 1. A capillary tube of inside diameter d=6mm connects tank A and open container B as shown in Fig.2. The liquid in A,B and capillary CD is water having a specific weight y=9780 N/m³ and a viscosity of μ=0.0008N s/m². The pressure PA-34.5 kPa gage. Neglecting the minor losses at C and D, determine the flow rate Q through the capillary tube. Assume laminar flow from A to B and use h=32μLV/yd² for the friction loss, where V is the water velocity through the capillary tube.
