File 1: THIS CODE IS USED TO DRAW THE PUMP CURVES AT DIFFERENT PUMP SPEED

1: PUMP CURVE

2: EFFICIENCY CURVE

3: BREAK HORSEPOWER CURVE

4: KW-INPUT CURVE



File 2: THIS CODE IS FOR APPLYING THE WAY OF CALCULATING THE EFFICIENCY, POWER

AND KW-INPUT FOR VARIABLE SPEED PUMP AT A GIVEN DESIRED HEAD AND DESIRED

FLOW AS SHOWN IN THE PAPER TITLED:

" how to calculate the pump efficiency and power for variable speed pump"



File 3: this code is to correct the use of affinity law by shifting the curve to

intersect with the system-curve at the desired flow as shown in the

paper titled:

"The Correct Method of Calculating Energy Savings to Justify Adjustable-Frequency Drives on Pumps"
