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 m2. The other end of the pipe (point B) is open to the air, has cross-sectional area 0.0120 m?, and is at a vertical height of 9.00 m above point A. Part 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.

A U shaped tube with diameter 2.00 cm, open to the air on both ends, contains mercury. Oil ispoured into the left arm until the oil column is 15.0 cm high. Then water is poured into the rightarm until the water column is 10.0 cm.a. On which side of the tube is the mercury level higher? Support your answer.b. What is the change in height of the mercury on both sides of the tube?c. To make the mercury return to its original level, which fluid would you have to add to thetube, and how much would you have to add (in cm cubed)?

A 6.6 cmcm diameter horizontal pipe gradually narrows to 4.2 cmcm When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 34.0 kPakPa and 23.4 kPakPa, respectively. Part A What is the volume rate of flow? Express your answer to two significant figures and include the appropriate units.
