Question
Bernoulli′s equation can be written in the following different forms (column A). Column B lists certain units each of which pertains to one of the possible forms of the equation. Match the unit associated with each of the equations :
(a)
= constant (i) Total energy per unit mass
(b)
= constant (ii) Total energy per unit weight
(c)
= constant (iii) Total energy per unit volume
(where z is ratio of height to volume)
(a)
= constant (i) Total energy per unit mass(b)
= constant (ii) Total energy per unit weight(c)
= constant (iii) Total energy per unit volume(where z is ratio of height to volume)
Options
A.a−(i), b−(ii), c−(iii)
B.a−(iii), b−(i), c−(iii)
C.a−(ii), b−(iii), c−(i)
D.a−(iii), b−(iii), c−(i)
Solution
Kinetic energy is 
mv2
∴
is energy per unit weight
is energy per unit volume and 
is energy per unit mass.
mv2∴
is energy per unit weight is energy per unit volume and is energy per unit mass.Create a free account to view solution
