A. Viscometer B. Manometer C. Hygrometer D. Tachometer
Explanation: A viscometer is an instrument used to measure the viscosity or flow rate of a liquid. It typically consists of a tube or container that holds the liquid and a device that measures the time it takes for the liquid to flow through a specific point in the container. The viscosity of a liquid is a measure of its resistance to flow and is affected by factors such as temperature, pressure, and composition.
