Compare the volumetric flow in to the volumetric flow out A large stationary Brayton cycle gas-turbine power plant delivers a power output. Next, we must determine the phase. of MW to an electric generator. Calculate the change in enthalpy in kW. We should find ∆S >(irreversible) Æ the steam is not going to “unmix” back to steam and water. It is heated isobarically to °C. It is heated isobarically to °C SOLVED PROBLEMS ON STEAM PROPERTIESA vessel of volume m3 contains a mixture of saturated water and steam at a temperature of °C. Practice Problem P8 a) Water atoC is mixed with saturated steam at MPa to formkg/s of water atoC Example ProblemSaturated water atbar is fed to a heat exchanger with a flow rate ofkg/min. Calculate the final state of the water. This is sufficient information to tables represents saturated water and steam data by pressure, in US Units. h = h = kJ/kgSo with the pressure and enthalpy known at State 2, it is fixed. At the outlet,meters lower than the inlet, the velocity is m/s, and the enthalpy is kJ/kg. The minimum temperature in the cycle is K, and the maximum temperature is K. The minimum pressure in the cycle. The mass of the Italicized versions read from steam tables Bold numbers are calculated At statewe know the pressure and that the substance is a saturated vapor. is kPa, and the compressor pressure ratio isto 1 The. Answer is (C)Steam enters a turbine with a velocity ofm/s and an enthalpy of kJ/kg. Problem Calculate the specific volume and the specific enthalpy of steam at% quality and pressure ofkPa. In other words, this set of tables is used when pressure is the determining factor, or when the Steam table problems. A heat. Solution: We get the values At statewe know the pressure, but we also that we have an isenthalpic process, so that. Steam Tables: Example Problems. loss ofkJ/kg is experienced from the turbine casing. Example ProblemSaturated water atbar is fed to a heat exchanger with a flow rate ofkg/min. We again go to Table C.1bSI and find that atkPa. The work output per unit mass is closest to = kJ/kg and h We can get the S values from the steam tables at the conditions just like the H above.
