Question

5) Starting with the hydraulic grade line at A (HGLA), sketch in the HGL and EL(energy line) between points A and B and label the velocity, pressure, and elevation heads

at points A and B. Assume no energy losses. Be as precise as possible when sketching and labeling. A steady flow of water enters and exits a nozzle section with uniform velocity profiles as shown in the figure below.The cross-sectional geometry of the nozzle is a square. At point A, the length of a side is a meters, and at point B, the length of a side is b meters. At point A, the velocity is VA m/s.
