Unformatted text preview: kg/s from 90 ºC to 60 ºC by water (cp = 4.18 kJ/kg/K) that enters at 15 ºC and leaves at 80 ºC. Determine a. the rate of heat transfer b. the mass flow rate of water 4. A 6-L evacuated rigid bottle is surrounded by air at 150 kPa and 25 ºC. A valve at the top of the bottle is opened and air flows into the bottle. Eventually, equilibrium is established between the bottle and the ambient. Determine the amount of heat transfer that occurs during the filling process. Use variable specific heats. 5. Simplify the general forms of conservation of mass and conservation of energy to analyze inflating a balloon. List all assumptions. Due Monday July 12, 2010 10:00AM...
