what is the steps to get the answer shown?

1. Water (=1000kgm3 and =0.0011kgm1s1) flows at 5ms1 over a 0.3m long flat plat. Determine if the flow in the boundary layer is laminar over the entire length of the plat or it becomes turbulent at a downstream location. If latter is the case, determine the location of transition from laminar to turbulent. [Ans. BL flow is Laminar \& turbulent, x=0.11m ]
