Ethanol is flowing in a pipe and at all points completely fills the pipe. At point AA in the pipe the gauge pressure is pp and the cross-sectional area of the pipe is 0.0500 m2m2. The other end of the pipe (point BB) is open to the air, has cross-sectional area 0.0200 m2m2, and is at a vertical height of 9.00 mm above point AA. Part A What must the gauge pressure pp be at AA if the volume flow rate out of the pipe at point BB is 0.0800 m3/sm3/s
