Determinación del Caudal

Q = Vol./t, en cm3/seg.

Vol. = 8lts.*(1000cm3/lt) = 8000cm3
* t1 = 54.95seg.
* t2 = 56.59seg.
* t3 = 57.04seg.

Q1 = 8000/54.95 =145.64cm3/seg.
Q2 = 8000/56.59 = 141.37cm3/seg.
Q3 = 8000/57.04 = 140.25cm3/seg.

ERRORMAX. = ((QMAX. – QMIN.)/QMAX. )*100<=2
= ((145.64-140.25)/145.64)*100 = 3.7% (valor permitido enel laboratorio)

Q = (Q1+Q2+Q3)/3
Q = (145.64+141.37+140.25)/3 = 142.42 cm3/seg
