1. A hole in the bottom of a large open tank discharges water to the atmosphere. If the exit velocity in the absence of losses is Ve, find the loss coefficient for the hole if the actual velocity is Ve/2. Assume turbulent flow. 2. Air enters a duct at a speed of 100 m/s and leaves it at 200 m/s. If no heat is added to the air and no work is done by the air, what is the change in temperature of the air as it passes through the duct?
