☆ Velocity
■ The scalar quantity whose negative gradient equals the velocity in the case of irrotational flow of a fluid.
☆ Fluid mechanics
■ In fluid mechanics, energy per unit
weight of fluid is termed as head. Now
this energy can be in the form pressure
energy, kinetic energy or gravitational
potential energy.
