Water is flowing in a round tube. The temperature is T = 25°C. p=997kg/m^3, and the dynamic viscosity is n = 8.91 x 10-4kg/m-s. The tube inside diameter is D = 100mm. What is the minimum velocity Vmin in m/s so that the flow can maintain turbulent?

Please answer fast. Will provide good rating

Using the appropriate equation from Table 4.3, calculate the wall sheer stress (in Pa) in a tube 5 mm in diameter with a flow rate of 1.3 Liters/minute. You may assume the fluid is Newtonian and has a viscosity of 1.9 cP. Do not include the unit label in you answer, only the numeric value.
