A piston–cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1 m3. Use the data from the steam tables.

A passive solar house was determined to lose heat to the outdoors at an average rate of 50,000
kJ/h during a typical 10-hour winter night. The house is to be maintained at 22°C at all times.
Passive heating is accomplished by 50 glass containers each containing 20 L of water that is
heated to 80°C during the day by absorbing solar energy. A 15-kW back-up electric resistance
heater turns on whenever necessary to keep the house at 22°C. (a) How many hours does the
electric heating system run during a typical winter night? (b) How many hours would the
electric heater run during a typical winter night if the house did not
have passive solar heating? For the density and specific heat of water
at room temperature, use p = 1 kg/L and cp = 4.18 kJ/kg.°C

At the Paso Robles Wastewater Treatment plant, they add MgCl2 to the pressate (concentrated liquid pressed from sludge) to precipitate phosphate as the mineral struvite. Struvite is formed by the reaction of phosphate with magnesium ions and ammonium, and the solubility product for struvite is 5.5x10-14. The ammonium concentration is very high at 300 mg N-NH4/L because the sludge is coming from an anaerobic digester. What minimum amount of MgCl2 (in mg/L) would be needed to precipitate all but 1 mg/L phosphate? Struvite precipitates by the following reaction: Mg++NH] +PO →MgNH PO 4 4 4arrow_forward
