Pressure Head

No, it can't. Dynamic head is 1/2 multiplied by the fluid density multiplied by the square of the velocity.

However, if there were two gauges and the fluid and the pipe diameter were known, then one might infer dynamic head from the two readings, assuming the gauges are accurate enough.

There may be a question of terminology here.

Velocity head = ρv²/2, but TDH (total dynamic head) includes elevation differences and pressure losses through the piping. [At least in one usage of language.]

One gauge alone will not indicate TDH, but subtracting the pump suction gauge reading from the discharge gauge reading gives the relevant information. (In case of negative readings, beware of arithmetic.)

Pressure guage does'nt indicate.
