Estimate the height which water will rise in a capillary tube 12mm diameter. Use surface tension = 0.0728 N/m and gamma = 9810 N/m^3  Ans. No Capillary Action

5.) A rectangular gate AB hinged at A has a width 2.0 m perpendicular to the paper, has a negligible weight. The water surface remains at the top of the gate. Determine the eccentricity of the hydrostastic force exerted by the water in meters from the centroid of the gate. Write your answer to the nearest whole number. Use unit weight of water 9.80 kN/m^3. fluid mechanics

Determine the hydrostatic force in liquid 1, 2 and 3

Problem 8: EGL and HGL (IV) Consider a storage reservoir with a water surface elevation of 270 m. It is connected to a closed conduit (i.e., a pipe) that carries water down to a turbine at elevation 60 m. The friction head loss in the conduit is 20 m. Part A At point D, what are the pressure head P/y, the elevation head z, and the HGL? Part B Copy the diagram below. If the conduit is a closed pipe flowing full, is the velocity head V²/(2g) constant D→E? Answer yes or no, then sketch the EGL above the pipe D-E. Use a solid line. D E z = 270 m T Part C Based on your answer to Part B, sketch the HGL from D-E. Use a dashed line. z = 270 m Part D Now assume the conduit is an open channel. Copy the diagram below. Is the velocity head V²/(2g) constant D→E? Answer yes or no, then sketch the EGL above the pipe D→E. Use a solid line. E D z = 60 m T z = 60 m Part E Based on your answer to Part D, sketch the HGL from D-E. Use a dashed line.
