Transcribed Image Text:A 12.0-m pipe is oriented 45 degrees from the horizontal,
delivering water (density 1000 kg/m³) from a river below to a
remote monitoring station by the edge of the mountain. The
base of the pipe is enclosed, and connected to a motor pump
that supplies water pressure of 509 kPa. The pipe has a
uniform diameter of 2.54 cm throughout. If the water speed
near the pump is 1.25 m/s, what is the absolute water
pressure as it exits the top of the pipe?
418 kPa
O 501 kPa
433 kPa
O 426 kPa
