Errores Porcentuales Aforo Caudales.docx

ERRORES PORCENTUALES En el siguiente apéndice presentamos los cálculos de error porcentual de los datos con ayuda de la ecuación 5, en el cual, consideraremos como el caudal teórico como Q1 correspondiente en cada apertura. 𝐸% =

× 100

Ec. 5

Primera apertura; 𝑉𝑇𝑒𝑜𝑟𝑖𝑐𝑜 = 1.60 × 10−4

𝐸% =

|1.60 × 10−4 − 1.60 × 10−4 | × 100 = 0% 1.60 × 10−4

𝐸% =

|1.60 × 10−4 − 2.30 × 10−4 | × 100 = 43.75% 1.60 × 10−4

𝐸% =

|1.60 × 10−4 − 2.82 × 10−4 | × 100 = 76.25% 1.60 × 10−4

Segunda apertura; 𝑉𝑇𝑒𝑜𝑟𝑖𝑐𝑜 = 3.59 × 10−4

𝐸% = 𝐸% =

|3.59 × 10−4 − 3.59 × 10−4 | × 100 = 0% 3.59 × 10−4

|3.59 × 10−4 − 4.11 × 10−4 | × 100 = 1.44% 3.59 × 10−4

|3.59 × 10−4 − 3.80 × 10−4 | 𝐸% = × 100 = 0.58% 3.59 × 10−4

Tercera apertura; 𝑉𝑇𝑒𝑜𝑟𝑖𝑐𝑜 = 4.62 × 10−4

𝐸% = 𝐸% =

|4.62 × 10−4 − 4.62 × 10−4 | × 100 = 0% 4.62 × 10−4

|4.62 × 10−4 − 4.23 × 10−4 | × 100 = 8.44% 4.62 × 10−4

|4.62 × 10−4 − 4.85 × 10−4 | 𝐸% = × 100 = 4.97% 4.62 × 10−4

Cuarta apertura; 𝑉𝑇𝑒𝑜𝑟𝑖𝑐𝑜 = 5.81 × 10−5 𝐸% =

|5.81 × 10−5 − 5.81 × 10−5 | × 100 = 0% 5.81 × 10−5

𝐸% =

|5.81 × 10−5 − 5.85 × 10−5 | × 100 = 0.63% 5.81 × 10−5

𝐸% =

|5.81 × 10−5 − 5.91 × 10−5 | × 100 = 1.72% 5.81 × 10−5
