What is the combined accuracy if water flow is measured through 3 meters 90 percent in meter 1 with 3 pcent accuracy 8 pcent in meter 2 with 10 pcent acc and 2 pcent in meter 3 with 15 pcent accuracy?

Answer 1

"3 meters measure water flow
90 percent thro meter 1 accuracy of 3 percent
8 percent thro meter 2 accuracy 10 percent and
2 percent thro meter 3 accuracy 15 percent what is accuracy combined?"



if in metre 1 (0.9 X 0.03) = .027
and in metre 2 (0.08 X 0.10) = .008
and in metre 3 (0.02 X 0.15) = .003

then total combined accuracy is 0.027+ 0.008 + 0.003 = 0.038 = 3.8 percent
