A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure). The upper end of the pipe is h1 = 1.90-m above the ground. The lower end of the pipe is h2 = 0.570-m above the ground. The water at the upper end of the pipe has a speed of 0.640 m/s. The water at the lower end of the pipe has a speed of 8.50 m/s. What is the pressure in the water in the pipe at the upper end of the pipe?
