Hi.

I am a not extremely proficient Excel user. I have been trying to figure
out how to tell Excel that I would like to create a formula.

I am trying to create this formula;

FL=C * Q2/100 * L/100
Where;
FL is Friction Loss
C is a varying Coeficient
Q is a varying Quantity in Litres divided by 100(then Squared)
L is Length in Meters divided by 100

C can equal 24.5 for 45mm
C can equal 3.17 for 65mm
C can equal .305 for 100mm

Looking for some help with this formula. For frequent users of excel
creating this formula may be simple, but I have been stumped! I will greatly
appreciate some assistance with this formula.

Thanks in advance.
