You need to cool 8.0 kg/s of superheated steam at 1000 kPa from 325oC to 200oC. You can either use R-134a that is available as a saturated liquid at 0oC, or air that is available at 15oC and 100 kPa. Due to other operational factors, the R-134a must not have an exit quality of greater than 0.60, and the air can not have an exit temperature greater than 75oC. Design a system that will meet the constraint for each substance, and comment on the relative practicality of each system.
Consider State 1 to be the steam inlet and State 2 to be the steam outlet. Consider State 3 to be the coolant inlet and State 4 to be the coolant outlet. Given: P1 = P2 = 1000 kPa; T1 = 325oC; m?s = 8.0 kg/s; T2 = 200oC Assume: Q? = 0 (insulated). Also, given no other information regarding the heat exchanger, make the following common heat exchanger assumptions: W? = ?KE = ?PE = 0 Also, assume the heat exchanger is a multiple-inlet, multiple-outlet, steady-state, steady-flow device. What will be an ideal response?
The disposal of manure should be handled by spreading it thinly on land that is not used for poultry
