water flows through the 30.0 cm diameter pipe shown in the figure. An open tube

Question

water flows through the 30.0 cm diameter pipe shown in the figure. An open tube is flush with an opening in the pipe at A and enters the pipe at B and is bent along the centerline of the pipe to face the oncoming flow. Water enters the tube and rises until the hydrostatic pressure in the tube balances the pressure at the mouth of the tube. Because no more water enters the tube, the speed of the water just outside the mouth of the tube is zero m/s. What is the manometer reading if the speed of the water in the pipe is 1.20 m/s? The manometer fluid is oil with a density of 800 kg/m^3, The correct answer is 9.18 cm. I'd appreciate a clear step by step explanation.
