Two streams discharge into a pipe as shown. The flows are incompressible. The volume flow rate of stream A into the pipe is given by Qa= 0.02t (m^3/s) and that of stream B by Qb= 0.008t^2 (m^3/s), where t is in seconds. The exit diameter of the pipe is 0.113 m. Find the flow rate, the velocity, and the acceleration of the flow at the exit at t=2 seconds.
