2. Compute the capillary depression for mercury in a glass capillary tube 3mm in diameter if the surface tension of mercury is 0.625 N/m and the wetting angle is 135 degrees. Given the specific gravity of mercury is 13.6.
18.A venture meter is a device that uses a constriction in a flow system to measure the velocity of flow, Figure 12 illustrate one type design. If the main pipe section is a standard hydraulic copper tube having a 100-mm outside diameter x 3.5-mm wall thickness, compute the volume flow rate when the velocity there is 3.0 m/s. Then, for that volume flow rate, specify the required size of throat section that would make the velocity there at least 15.0 m/s.
Compute points on the velocity profile from the pipe wall to the centerline of a 3/4-in Type K copper tube if the volume flow rate of water at 60'F is Q 0.5 gal/min. Use increments of 0.05 in and include the velocity at the centerline.
