1.Two vertical, parallel, clean, glass plates are spaced a distance of 2.3 mm apart. If the plates are placed in water how high will the water rise between the plates (in mm) due to capillary action? Use a value of 0.073 N/m for the surface tension for water.
2.Liquid flows with a free surface around a bend. The liquid is inviscid and incompressible, and the flow is steady and irrotational. The velocity varied with the radius across the flow as V = 1/r m/s where r is in meters. Find the difference in depth of the liquid from the inside to the outside radius. The inside radius of the bend is 1 m and the outside radius is 3 m.
