Question

A liquid flows into a vessel initially empty at a steady
rate of 70 cm’s-1. The pictorial representation
(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.

please answer this correctly and as fast as possible.​

Answer 1

Answer:

(i) calculate L.C.

=pitch number of division on circular scale

(ii) P.S.R = nth division × pitch

(iii) Observed reading =P.S.R +(H.S.R×L.C.)

(iv) Zero error =[H.S.R. + (N -n) ×L.C.]

(v) Corrections is positive if error is negative

(vi) Correct measurement = observed reading + correction.

(vii) Correct measurement =7.25 mm
