Air, assumed incompressible, flows through the two pipes shown in Fig. P8.82. Determine the flowrate if minor losses are neglected and the friction factor in each pipe is 0.020. Determine the flowrate if the 0.5-in.-diameter pipe were replaced by a 1-in.-diameter pipe. Comment on the assumption of incompressibility.
