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..

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
