Which of the following statements about HGL and EGL is correct? O For any pipe will a constant wall thickness, the slopes of EGL and HGL will be constant. O If the EGL falls below the pipe, then pressure head is negative, indicating a potential location of cavitation. O When a flow passage decreases in diameter, the distance between the EGL and HGL will increase. O When a pipe discharges into the atmosphere, both HGL and EGL will coincide with the system because pressure head is zero at these points.
