| Q. |
between EGL and HGL |
| A. | increases |
| B. | decreases |
| C. | remains constant |
| D. | may increase or decrease |
| Answer» B. decreases | |
| Explanation: the vertical intercept between egl and hgl is equal to the kinetic head. for a diffuser, the cross-sectional area increases in the direction of flow leading to a decrease in the velocity of flow across the pipe. since the kinetic head decreases, the vertical intercept between egl and hgl will decrease. | |
