Velocity data for air are collected at different radii from the centerline of a circular 16-cm- diameter pipe as tabulated below: 1, cm 1.60 3.20 4.80 6.40 7.47 7.87 7.95 8 v, m/s |10 9.69 9.30 8.77 7.95 6.79 5.57 4.89 0 a) Determine the mass flow rate, which can be computed as R pv2nr dr where p = density (= 1.2 kg/m). Express your results in kg/s. b) Using any suitable root-finding technique, estimate the time for the water velocity to achieve 5 cm. c) Explain other methods than root-finding technique to get answer for QUESTION b.
