Задача 32 Определить внутренний диаметр

Task 32 Determine the inner diameter of the pipeline through which water is supplied with a flow rate of Q = (0.29 + 0.02 j) l / s, from the condition of obtaining the maximum possible speed in it while maintaining the laminar regime, the liquid temperature is 20 ° C.
Q = (0.29+0.02j) = (0,29+0,02*10) = 0,49 l/s
