Question

The mass of the liquid flowing per second per unit area of
cross-section of the tube is proportional to (pressure
difference across the ends)ⁿ and (average velocity of the
liquid)ᵐ. Which of the following relations between m and n
is correct?
(a) m = n (b) m = – n
(c) m² = n (d) m = – n²

Answer 1

Answer:

M/At]=[P

m

⇒ n=1,m−n=−2

or, m=−1

∴ m=−n
