What are the three advantages of using steam in a process? 10. saturated steam at 1 atm is discharged from a turbine at a rate of 1,200 kg/h at 100°c [h-2676 kj/kg). superheated steam at 300°c[h-3074 kj/kg) and i atm are needed as a feed to a heat exchanger, to produce it, the turbine discharge stream is mixed with superheated steam available from a second source at 400°c [specific h-3278 kj/kg) [specific v=3.11 m /kg) and 1 atm. the mixing unit operates adiabatically. calculate the amount of superheated steam at 300°c produced and the required volumetric flow rate of the 400°c steam. draw the pfd.

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
