Referring to the figure shown, identify the true statements about the characteristics of the hydraulic grade line (HGL) and energy grade line (EGL) from the following. (Check all that apply.)Group of answer choicesThe gage pressure of a fluid is zero at locations where the HGL intersects the fluid.At a pipe exit, the pressure head is zero (atmospheric pressure), and thus the HGL coincides with the pipe outlet.The EGL is always a distance V^2/2g above the HGL.For stationary bodies such as reservoirs or lakes, the EGL and HGL coincide with the free surface liquid.The mechanical energy loss due to frictional effects causes the EGL and HGL to slope upward in the direction of flow.For open-channel flow, the EGL and HGL coincide with the free surface of the liquid.In an idealised Bernoulli-type flow, EGL is horizontal and its height remains constant.A steep increase occurs in EGL and HGL whenever mechanical energy is removed from the fluid.
