Candidates should be able to:
(a) define the term pressure in terms of force and area
(b) recall and apply the relationship pressure = force / area to new situations or to solve related
problems
(c) describe and explain the transmission of pressure in hydraulic systems with particular reference to
the hydraulic press
(d) recall and apply the relationship pressure due to a liquid column = height of column × density of the
liquid × gravitational field strength to new situations or to solve related problems
(e) describe how the height of a liquid column may be used to measure the atmospheric pressure
(f) describe the use of a manometer in the measurement of pressure difference
