VBA for Point of Intersection between 2 Curves

[kurayveth~]

Hi, i really need a help here asap by tomorrow. I would appreciate if someone could send me the VBA codes for this question i have as an assignment.

The criteria of the assignment is as below :
For this problem you will be provided with your own set of pump and system curves. You must therefore:

1. Find suitable polynomial expressions for the system and pump curves
2. Write a Newton Raphson function that returns the flowrate at the duty point
3. Write a function for the Newton Raphson to solve – this may include the first derivative as well.

When putting together your code, you should keep the following points in mind:

1. You will need at least 3 separate functions; the Newton Raphson function itself and the two others that return values of f(x) and f’(x)
2. That you have a single function call that takes the specified coefficients of the pump and system curve, along with any other values you see fit.

The data is given as below

Flowrate	System head	Pump head
m3/hr	m	m
0	15.35	33.22
10	15.26	33.10
20	15.27	33.08
60	15.80	32.79
90	16.76	32.46
100	17.22	32.34
110	17.72	32.20
170	22.34	30.95
210	27.10	29.50
220	28.51	29.08
230	30.01	28.58
