You are comparing distillation column designs at 1 atm and 3 atm total pressure for a particular separation. You have the same feed in both cases, and the feed is a saturated liquid in both cases. The product specifications do not change, and the same reflux ratio is used in both cases.

Compared to the design at 3 atm, the design at 1 atm will have: (Select one) a) more stages, fewer stages, the same number of stagesb) a larger diameter, a smaller diameter, the same diameterc) a higher reboiler temperature, a lower reboiler temp, the same reboiler temp

Air enters a compressor operating at steady state at a pressure of 1?, a temperature of 290 K, and a velocity of 6 m? through an inlet with an area of 0.1 m2. At the exit, the pressure is 7?, the temperature is 450 K and the velocity is 2 m?. Heat transfer from the compressor to its surroundings occurs at a rate of 180? m?. Employing the ideal gas model, calculate the power input to the compressor in? W.

An ECE110 student decides to "go off the grid" and powers his house by batteries. On the first day, the electric power usage for the household was 29 kW-h. He must recharge his batteries using a bicycle-powered generator with 92 % efficiency. For how many hours must he now pedal the bicycle at a peak power of 560 W in order to recharge to the batteries?

Suppose you were doing an A * search and there were a number of different ways that you could compute an admissible heuristic value. Suppose that some were very cheap to compute but also very inaccurate estimators while others were very expensive to compute but were very accurate estimators. How would you determine which computation to use for a given application?

Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/min to an adiabatic turbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine the steam flows to a heater, where it is reheated isobarically to its initial temperature. Neglect kinetic energy changes. Write an energy balance on the turbine and use it to determine the outlet stream temperature. Write an energy balance on the heater and use it to determine the required input (kW) to the steam. Verify that an overall energy balance on the two-unit process is satisfied. Suppose the turbine inlet and outlet pipes both have diameters of 0.5 meter. Show that it is reasonable to neglect the change in kinetic energy for this unit.
