ater flows along a streamline through the pipe shown in the figure below. Point A is higher than points B and C and the pipe has a constant radius until it expands between B and C. HINT Three locations are marked on a pipe through which water flows. The first part of the pipe is horizontal, and water flows to the right. Location A is labeled in the middle of this portion. The pipe then makes a 90 degree turn and flows downward, then makes a second ninety degree turn and flows horizontally rightward again. Location B is marked right after this second 90 degree turn. The pipe continues horizontally and widens to approximately twice the width of all previous portions. Location C is marked after the pipe widens. (a) From highest to lowest, rank the flow speeds at points A, B, and C. vA > vB > vC vA = vB = vC vB > vC > vA vB = vC > vA vA = vB > vC (b) From highest to lowest, rank the pressures at points A, B, and C. PA = PB = PC PB = PC > PA PC > PA = PB PC > PB > PA PA = PB > PC
