As a result of energy conservation measures, a chemical manufacturing facility has an abundant supply of low-pressure steam. Cooling water is also available, and the plant engineers are considering the possibility of using these resources to produce chilled water for air conditioning. Assume steam will enter the chiller saturated at P=1 atm and will leave as condensate, also saturated at P=1 atm. Cooling water enters the chiller at T=80

Unformatted text preview: ° F and leaves the chiller at T=100 ° F. Chilled water enters the chiller at T=75 ° F and leaves at T=55 ° F. What is the cooling water flow rate and the maximum amount of chilled water produced per lb of steam? 5. A tank of 10 m 3 volume contains an ideal gas (C P =30 J/mol-K) at T=298 K and P=5 bar. If gas from the tank is allowed to flow through a reversible device and exhaust to the atmosphere at P=1 bar, what is the maximum work that could be obtained if both the tank and the reversible device could be kept isothermal at T=298 K?...
