Final answer:
The statement is likely false as manometers measure pressure differences and are not typically used to measure drag forces on cylinders; other instruments like wind tunnels and force sensors are more suitable for this purpose.
Step-by-step explanation:
The statement regarding the use of a multi-tube manometer to measure the drag on a circular cylinder, which consists of skin friction drag and pressure drag (or form drag), is likely false. Manometers are devices commonly used to measure pressure rather than drag forces. In the context of fluid dynamics, a manometer measures pressure differences, which could be related to fluid statics demonstrated in the barometer, or fluid dynamics such as the one described in Bernoulli's principle. However, to measure drag on a cylinder, one would typically use a different set of instruments and techniques, such as a wind tunnel with force sensors.
