Can you only show how to setup the problem to get the answer, thank you

The air at atmospheric pressure and temperature of 30C flows over one side of plate of a velocity of 90m/min. This plate is heated and maintained at 100C over its entire length. Find out the following at 0.3 and 0.6m from its leading edge. (a) Thickness of velocity boundary layer and thermal boundary layer. (b) Mass flow rate which enters the boundary layer between 0.3m and 0.6m per metre depth of plate. Assume unit width of plate. Properties of air at 30C:=1.165kg/m3,v=16106m2/s,Pr= 0.701,Cp=1.005kJ/kgK,k=0.02675W/mK Given Data: T=30CTs=100Cu=90m/minx1=0.3mx2=0.6mb=1m To be Calculated: a) 1,2,th1,th2= ? b) m=
