Superheated steam at 40 bar absolute and 500°c flows at a rate of 250 kg/min to an adiabatic turbine, where it expands to 5 bar. the turbine develops 1500 kw. from the turbine the steam flows to a heater, where it is reheated isobarically to its initial temperature. neglect kinetic energy changes. a. write an energy balance on the turbine and use it to determine the outlet stream temperature. (7 marks) b. write an energy balance on the heater and use it to determine the required input power (kw) to the steam. (6 marks) c. verify that an overall energy balance on the two-unit process is satisfied. (6 marks) d. suppose the turbine inlet and outlet pipes both have a diameter of 0.5 meter. show that it is reasonable to neglect the change in kinetic energy for this unit

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback

Nthis lab, you will do experiments to identify types of changes. using the question format you learned (shown above), write an investigative question that you can answer by doing these experiments
