Determine the motor size required to pump 1000 cfs through a 10,000 ft long 12.0 ft diameter pipeline to an upper reservoir 2000 ft above the reservoir. Use a friction factor of 0.02 and pump efficiency of 80 percent. Compute the energy input to the motor, if the motor efficiency is 90%.

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
