Ethanol is flowing in a pipe and at all points completely fills the pipe. At point A in the pipe the gauge pressure is p and the cross-sectional area of the pipe is 0.0500 m. The other end of the pipe (point B) is open to the air, has cross-sectional area 0.0160 m, and is at a vertical height of 7.00 m above point A What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m/s? Express your answer with the appropriate units. p= Value Submit Request Answer Units ?
