2C What is minor loss in pipe flow? How is the minor loss coefficient K defined?
8-63 Water is to be withdrawn from an 8 m high water reservoir by drilling a 2.2 cm diameter hole at the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole if a) the entrance of the hole is well-rounded and b) the entrance is sharp-edged.
8-64 Consider flow from a water reservoir through a circular hole of diameter D at the side wall at a vertical distance H from the free surface. The flow rate through an actual hole with a sharp-edged entrance (K = 0.5) is considerably less than the flow rate calculated assuming frictionless flow and thus zero loss for the hole. Disregarding the effect of
