Gasoline flows through a horizontal pipeline with a flow rateof 25 ft3/min. A pressure gauge measures thepressure to be 315lbs/ft2 in a section of the pipelinewith a diamteter of 4.2-in. If the line expands to a pipe with adiameter of 6.5-in, What are:
a) the flows speed in the larger diameter pipe (ft/s) ?
b) the pressure in this pipe (lbs/ft2) ?
