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 can be 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.) Using the figure below, suppose that the flow rate of liquid water, Q, is 800 gpm (gallons per minute). 1. IfD= 12 in, what is the velocity (ft/s) of the water before it enters the venturi? 2. Would you recommend a venturi diameter (D:) of 0.15 in? (A simple yeso will not suffice. No calculations and reasoning, means no credit.) . pressure taps JU D Q d D Venturi Meter Parameters
