Question

Can someone explain to me how to do a comparison in percent basis for the following fixtures and valves?

The table contains the calculated resistance coefficient K and the tabulated coeffiecient K for different fixtures. Thank you, will rate.

Calculated Resistant coef K	Tabulated K
0.138095449	0.38
1.380954487	0.28
2.485718077	2.16
5.938104295	3.24
8.730221649	9.5
7.390663829	0.22
0	0
-4.988698085	0.08

Answer 1

The comparison between experimental values and those obtained by calculation from mathematical model can be done by finding the percent error in the tabulated (experimental) value with respect to the calculated value.

% error= (K_tabulated-K_calculated)/(K_calculated)

Calculated(theoretical) Resistant coef K	Tabulated(experimental) K	% Error
0.138095449	0.38	175.1
1.380954487	0.28	-79.724
2.485718077	2.16	-13.1035
5.938104295	3.24	-45.43
8.730221649	9.5	8.81739
7.390663829	0.22	-97.023
0	0	0
-4.988698085	0.08	-101.6036
