CHEMICAL ENGINEERING TECHNOLOGY: FLUID MECHANICS DURATIO N Week 1-2. . . Definition The study of f1uids in motion, where pressure forces are not considered, is called fluid kinematics and if the pressure forces are also considered for the fluids in motion. Many devices are based on hydrostatics such as barometers and manometers, i.e., determine pressure through measurement of a column (or columns) of a liquid using the pressure variation with elevation equation for an incompressible fluid. Let X be the centre of the pipe. … .
