What is a system curve?
a System curve is used in hydrolic anylyses to dtermine the duty point of a pump for a certain pipe line. The pump curve and system curve are plotted on the same graph and where the two cross each other is the duty point, the curve is a Head(meters) vs Flow(m3/hour). The system curve Head = static head + head loss due to friction in pipe + secondary head loss *This is calculated for a certain flow to determine the Head so it can be plotted on the curve
What is the difference between the hydraulic grade line and the energy line?
Hydraulic grade line is sum of Datum + Pressure Head Energy grade line is sum of Datum + Pressure Head + Velocity Head
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
What is an example of contemporary use of the real number system in business?
An example of contemporary use of real number system in business is a mathematician which his/her job is to come up with the next numbers in the number line which still doesn't have an end. So mathematician will use a number line everyday that they work.
When you graph a system and all you see is one line how many solutions will the system have?
If you graph a system of two lines and all you see is one line, this means that both lines are the same. Any point on the line is a solution, so the system has an infinite number of solutions.
