A heat engine operating on the Carnot cycle uses solar energy as the source of high-tem- perature heat input. The solar irradiation, averaged over the day, has a value of q'ux =0.51 kW/m?. This provides energy to the cycle at a uniform temperature of 450 K, and the cycle rejects heat to the environment at a temperature of 300 K. The engine produces 2000 kW of power. During solution, the following parts must be in order. (a) Sketch the system and its boundary, with all the given data displayed on it. (b) Draw the temperature-entropy (T-s) diagram of the cycle. Assume start of heat addi- tion is state point 1 and all the given data displayed on it. (c) Determine the minimum area of the solar panel in acres that is needed to provide this power. Write down units in each step of the solution, where appropriate. Write your comments on the outcome of your solution. Use correct and appropriate symbols for the known and unknown thermodynamic quantities and properties.

A hot benzene vapor stream at 500oC and 1 bar is rapidly cooled by mixing with liquid benzene at 25oC and 1 bar. The stream leaving the mixer must be 200oC and 1 bar. Assume the reactor is at constant volume. Determine the flow rate (in mol/hr) of the liquid benzene feed stream assuming the flow rate of the hot benzene vapor stream is fixed at a certain value x (specified in the quiz question). Use the polynomial approximations for heat capacity and Table B.20 when appropriate. Assume the flow rate of the hot benzene vapor stream is fixed at 1,253 mol/hr and the liquid benzene feed stream is your reference state. What flow rate (mol/hr) of the liquid benzene feed stream must be used? Round your answer to the nearest tenth and do not include units. Use Tables B.17 and B.20 to tabulate relevant data. Remember that temperatures for polynomial heat capacities are in Kelvin.
