Steam passes steadliy through a turbine and condenser as shown in the figure below. After expanding through the turbine and producing 1000kW of power, the steam is at a pressure of 0.08 bar and a quality of 87.4%; it enters a shell-and-tube heat exchanger where the steam now condenses on the outside of tubes through which cooling water flows; this condensate continues to flow, finally exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing steam is 58kg/s, In order to condense the steam, cooling water enters the tubes at 15°C and flows as a separate stream to exit at 35°C with negligible change in pressure. Stray heat transfer is negligible as are kinetic and potential effects. Considering the steam inside the turbine as a system, is the system best described as open, closed or isolated? What is the mass flow rate of steam entering the turbine in kg/s? What is the enthalpy at the inlet of the turbine in k/kg? What is the mass flowrate of the cooling water in kg/s?…

9. A vapour compression plant is powered by a 2kW motor and circulates R12 at 5kg/min. The R12 leaves the condenser at its saturation temperature with a specific enthalpy of 74.59kJ/kg and leaves the evaporated dry saturated with a specific enthalpy of 187.53kJ/kg. Calculate: (a). the dryness fraction at the evaporator inlet (b). refrigeration effect (c). coefficient of performance
A straight-condensing 10,000 kW turbine has a guaranteed steam rate of 5.90 kg/kW.hr when exhausting at 5.0 kPa. Exhaust steam enters the condenser at 92% quality, and it is estimated that fouling will decrease the overall coefficient by 30% during operation. Cooling water is available at 18 ℃, and for design purposes, 1 ½ in OD 16 BWG Brass tubes (thickness = 0.065 in, k=62 BTU/hrftF°.) are specified with 9 C° rise in cooling water, which circulates at 5 ft/s. Inside and outside film coefficients are hi=960 and ho=1474 BTU/hrft2F°. Design a condenser for this turbine, considering tube and boundary resistance as flat surfaces and neglecting any crossflow factor. Determine the followinga) Effective overall coefficient of heat transferb) Volume flow rate of cooling waterc) Number of tubes for single passd) Length of tubes
