Part A Ethanol is flowing in a pipe and at all points completely fills the pipe. At point A in the pipe the What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is gauge pressure is p and the cross-sectional area of 0.0800 m /s? the pipe is 0.0500 m- The other end of the pipe (point B) is open to the air, has cross-sectional Express your answer with the appropriate units. area 0.0200 me, and is at a vertical height of 9.00 m above point A. HA ? XD X . 101 X N P= 40000 2 m
