A liquid flows into a vessel initially empty at a steady rate of 70 `cm^(3) s^(-1)` . The pictorial repressentation (graph) of the increase in the mass of the vessel with time is given below.
(i) What does the point A represent ?
(ii) What does the horizontal line beyond B indicate ?
(iii) find the capacity of the vessel.
(iv) Find the density of the liquid .

(i) calculate L.C.
`=("pitch ")/("number of division on circular scale ")`
(ii) P.S.R = nth division `xx` pitch
(iii) Observed reading =P.S.R +(H.S.R`xx`L.C.)
(iv) Zero error =[H.S.R. + (N -n) `xx`L.C.]
(v) Corrections is positive if error is negative
(vi) Correct measurement = observed reading + correction.
(vii) Correct measurement =7.25 mm
