On a hot day (t = 30°c), a truck moves along the highway at 29 m/s. the flat side of the truck is treated as a simple, smooth flat plate boundary layer to first approximation. estimate the x-location along the plate where the boundary layer begins to transition to turbulence. how far downstream from the beginning of the plate do you expect the boundary layer to become fully turbulent? the density and viscosity of air at t = 30ºc are 1.164 kg/m3 and 1.872 × 10–5 kg/m·s, respectively..

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
