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

what is the difference between division and grade

you ve spelt them the same sorry i don't know what you meen.

A D is a passing grade for 9th grade. It is the overall average of all grades that makes the difference between passing and repeating a grade.

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.

A total energy line is a line on a pump curve that represents the total energy of a fluid flow system, combining both the pressure head and velocity head of the fluid at any point in the system. It is used to analyze and optimize pump performance and system efficiency.

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

The main difference is in between grade A,B & C IS THE CARBON CONTAIN OF THE MATERIALS.

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.
