6liquid water at 200 kpa and 15°c is heated in a chamber by mixing it with superheated steam at 200 kpa and 150°c. liquid water enters the mixing chamber at a rate of 4.3 kg/s, and the chamber is estimated to lose heat to the surrounding air at 20°c at a rate of 1200 kj/min. if the mixture leaves the mixing chamber at 200 kpa and 80°c, determine

(a) the mass flow rate of the superheated steam and
(b) the rate of entropy generation during this mixing proce

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
