Carol and Dan run a 50 meter race along a straight horizontal track. They start at the same position at the same time. Carol runs with constant speed. During the race, Dan stops for a few seconds to tie his shoe. Other than this interruption, Dan runs with constant speed. They cross the finish line at the same time. Who has the larger average velocity for the whole race? Who has the larger speed when they cross the finish line?

Oxygen gas enters well-insulated diffuser at 25 lbf/in.2, 420r, with a velocity of 860 ft/s through a flow area of 1.6 in.^2. at the exit, the flow area is 12 times the inlet area, and the velocity is 19 ft/s. the potential energy change from inlet to exit is negligible. assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the following: (a) the exit temperature, in r(b) the exit pressure, in lbf/in.^2 (c) the mass flow rate, in lb/s
