When a steadily flowing gas flows from a larger-diameter pipe to a smaller-diameter pipe, what happens to (a) its speed, (b) its pressure, and (c) the spacing between its streamlines?
Step 1 of 3
Solution 47E The continuity equation can be used here, which states that Av = constant where A = cross section and v = speed. The gas flows to a smaller diameter pipe. Hence from the above equation, cross-section decrease is accompanied by an increase in speed. When there is an increase in speed, there will be a decrease in pressure. The pipe gets narrower, hence the streamlines get loser.
