Aperson steps off the end of a 3.45 � high diving board and drops to the water below. (a) how long does it take for the person to reach the water? (b) what is person’s speed on entering the water? (c) what is person’s speed on entering the water if they step off a 12.0 � diving

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
