Question: Water flows in a tank of diameter d = 1 m with an input volume flow rate qi = 0.1 m3 /s. At the base of the tank is a discharge pipe of length l = 3 m and inner diameter di = 40 mm. Find the output flow rate exiting the pipe after t = 20 s and the difference between the input and output flow rates as time goes to infinity (the steady-state error). Known are: n = 0.001 N-s/m2 and t = 1000 kg/m3 .
