A power plant in rough terrain has a 100-m stack with an inside radius of 1 m. The plant emits 300 g/s of SO2 from the stack with an exit velocity of 10 m/s at a temperature of 120oC. Ambient temperature is 6oC and the temperature increases at a rate of 2 K/km. At 10 m above ground, surface windspeed is 1.5 m/s on a mostly cloudy night. Find the concentration (mg/m3) of SO2: Directly downwind at a distance of 2 km. At a point located 2 km downwind and 0.1 km off the downwind axis. At the point downwind where it is a maximum. Approximately how far from the stack does this occur?

An insulated piston-cylinder device contains 4 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 8A flows for 50 min through a resistor placed in the water. If one-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 300 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to the saturation lines.
