Water fl ows from a pressurized tank as shown. Th e pressure in the tank above the water surface is 100 kPa gage, and the water surface level is 8 m above the outlet. Th e water exit velocity is 10 m/s. Th e head loss in the system varies as hL = KLV 2 /2g, where KL is the minor-loss coeffi cient. Find the value for KL. Assume α = 1.0 at all locations.
