2. Air flows in a steady manner through a converging tube. At the inlet there are 690kPaa and 1.193m/kg. If 125m/min of air enters at the rate of 1.57 m/sec and the exit section has a diameter of 35cm, determine (a) the mass flow rate in kg/sec, (b) the diameter of the entrance section in mm and (c) the exit velocity in m/min.

A ball is thrown vertically upward from the ground and a student gazing out the window sees it moving upward pass him at 5 m/s. The window is 1000cm above the ground. How high does the ball go above the ground?
