Question

ANS. All i
15. Volume V of water which passes any point of a
canal during t second is connected with the cross
section A of the canal and the velocity u of water
by the relation V = KAtu, where K is
dimensionless constant. Verify the correctness
of the relation.
[Ans. Correct]
non velocity from the surface of earth is
​

Answer 1

Answer:

The relation is correct.

Step-by-step explanation:

The given relation is

V = KAtu

Were

V = Volume of water

A = cross sectional area

t = sime in second

u = velocity of water

Dimensions of V = $[L^3]$

Dimensions of A = $[L^2]$

Dimensions of t = $[T]$

Dimensions of u = $[LT^{-1}]$

Therefore,

Dimensions of KATu

$=[L^2][T][LT^{-1}]\\=[L^{2+1}T^{1-1}]\\=[L^3T^0]$

$=[L^3]$

Since, the dimensions of both the sides of the relation are equal

Therefore, the relation is correct.
