Hi. i have a real experiment in fluid mechanics lab. i have a 19cm diameter pipe with air flowing in it. the velocity profile measured using pitot static tube is given by the equation: v = -0.0008*x^4 + 0.0367*x^3 - 0.5694*x^2 + 3.1673*x + 6.154 where v is the velocity in m/s, and x is the distance from the bottom of pipe. it is required to find the volume flow rate inside this pipe.
