It is proposed that a 1,000-MW electric power plant be built with steam as the working fluid with the condenser to be cooled with river water. The maximum steam temperature is 550o C, and the pressure in the condenser is 10 kPa. The river, which is about 60 m wide and 8 m deep, has an average velocity of 10 m/min. Estimate the temperature rise of the river downstream from the power plant, in o C.

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
