Electronic components are attached under a thin square plate and the all the energy dissipated by components is removed by water flow over the top surface. The plate length is 0.17 m and the thermophysical properties of water may be approximated as: k = 0.620 W/mK, Pr = 5.2, v = 0.96x10-6 m²/s water dissipated energy from the components V m/s 20°C Water flow velocity is 2 m/s and the amount of dissipated energy (q') from the components can be estimated as uniformly distributed heat flux of 75000 W/m². One approach to analyze this problem is to assume the plate has an isothermal temperature as a boundary condition.

Question
![Electronic components are attached under a thin square plate and the all the energy dissipated by components
is removed by water flow over the top surface. The plate length is 0.17 m and the thermophysical properties of
water may be approximated as:
k = 0.620 W/mk, Pr = 5.2, v = 0.96x10-6 m²/5
water
V m/s
20°C
_q" W/m?
dissipated energy from
the components
Water flow velocity is 2 m/s and the amount of dissipated energy (q") from the components can be estimated
as uniformly distributed heat flux of 75000 W/m2. One approach to analyze this problem is to assume the
plate has an isothermal temperature as a boundary condition.
Calculate the average isothermal plate temperature in °C for the given conditions
If the boundary layer is 'tripped' and the flow over the plate is completely turbulent; what will be the average
isothermal plate temperature in °C for this case?
