What is the difference between hydraulic grade line and energy grade lines?
Energy gradient line refers to total energy excluding the losses due to flow. ie) Datum Head + Pressure Head + Velocity Head Hydraulic gradient line refers to the line joining upper and lower water surface levels excluding losses and velocity head. ie) Datum Head + Pressure Head

Difference between elementary algebra and intermediate algebra?
Elementry Algebra is something that 6th, 7th, 8th and even, 9th graders take.The basic standard is6th grade: Junior High Mathematics7th grade: Transition8th grade: Algebra9th grade: Geometry10th grade: Algebra 211th grade: TrigonometryAnd so on so forth.So the difference is the grades and what level you are in.

What is total energy line?
The Hydraulic Grade LineThe Hydraulic Grade Line is a line representing the total head available to the fluid - minus the velocity head and can be expressed as:HGL = p / γ + h (4)whereHGL = Hydraulic Grade LineThe hydraulic grade line lies one velocity head below the the energy line.The Hydraulic Grade Line is a line representing the total head available to the fluid - minus the velocity head and can be expressed as:HGL = p / γ + h (4)whereHGL = Hydraulic Grade LineThe hydraulic grade line lies one velocity head below the the energy line.
What is the difference between energy line and energy grade line?
Difference between energy line and energy grade lineThe line showing the total energy at any point in a pipe. The total energy in the flow of the section with reference to a datum line is the sum of the elevation of the pipe centerline, the piezometric height (or pressure head), and the velocity head. The energy grade line will slope (drop) in the direction of flow except where energy is added by mechanical devices. The line representing the elevation of the total head of flow is the energy line. The slope of the line is known as the energy gradient

What is difference between low grade energy high grade energy?
Low-grade energy: Based on the thermodynamic concepts, an energy source can be called as high-grade or low-grade, depending the ease with which it can be converted into other forms. Thus electrical energy is called a high-grade energy, as it is very easy to convert almost all of it into other energy forms such as thermal energy (say by using an electrical heater). Whereas, it is not possible to convert thermal energy completely into electrical energy (typical efficiencies of thermal power plants are around 30 percent), hence thermal energy is called a low-grade energy. Naturally, high-grade energy sources are more expensive compared to low-grade energy sources.
