2. the term steady state refers to a system in which flows of mass, heat, and work of a system do not change over time. a venturi meter is a steady state device that measures the flow rate of a liquid by producing a pressure drop. the pressure drop is measured using a manometer; however, this pressure is produced by significantly reducing the diameter of a pipe, causing the velocity of the fluid to increase. (in other words, at steady state the increase in velocity produces a decrease in pressure.) in the figure below, the flow rate of liquid water, q, is 1,000 gpm (gallons per minute) and d1 is 10 cm. what is the velocity at d1 (i. e. v1) in ft/s? what is d2 if v2 is 200 ft/s?
hint: flow rate, q, is fluid velocity times the cross-sectional area (i. e. area of a circle with diameter, d)
