An array of 190 electrical components, each dissipating P = 35 W, are attached to the bottom surface of a square copper plate. The length of the edge of the square plate is L= 0.1 m. All of the energy dissipated in the electrical components is transferred to water flowing over the top surface of the copper plate. The water flow over the plate in a direction that is parallel to the edge of the plate. A proturbence at the leading edge of the plate acts to trip the bounary layer into turbulent flow. The plate may be assumed to be isothermal since the thermal conductivity of copper is so high. The water velocity and temperature far from the plate are uo = 2.3 m/s and Too = 22 °C. The water's thermophysical properties (for application in correlations for the Nusselt number) may be approximated as v = 0.96x10-6 m²/s, kf = 0.62 W/m-K, and Pr = 5.2. What is the temperature of the copper plate in °C?

A thin outer border of a building's area covers 10×10m^2. The sky temperature is 300K meanwhile the temperature of the sun is 5800K. The overall distance between the sun and earth is 1.5×10^11 meters and the overall sun diameter is 1.4×10^9 meter and the earth diameter is 1.3×10^7 meters. The properties of the outer border are: ελ = 0.5 for λ > 6 µm & ελ = 0.1 for λ < 6 µm. The outer border can be considered a diffuse surface. Air current flows over the border with a velocity of 10 meters/second with a temperature of 300K. Beneath the border, the air inside the building flows over the bottom side of the border at 1 meter/second. Determine the steady-state temperature of the border for these conditions.

A wire of length L1=30cm has a fixed end and the other end is welded to another wire, whose linear mass density is 4 times smaller. The second wire passes over a pulley and a mass of 10kg is suspended from its other end.The distance L2 between the welding point and the pulley is 80 cm.
