Velocity head is the mechanical energy of a fluid per unit weight of the fluid measured relative to the bottom of the channel. a. True
b. False

b. False

Explanation:

The Bernoulli's equation is given by;

Divide through by the density of the fluid and acceleration due to gravity (ρg), to obtain energy per unit weight of the fluid known as head;

where;

is pressure head

h is datum head (mechanical energy due to height of the fluid)

is velocity head (mechanical energy due to velocity of the fluid)

Thus, the mechanical energy of a fluid per unit weight of the fluid, measured relative to the bottom of the channel is datum head.

The correct option is "b. False"
