Atank contains 21 kg of dry air and 0.3 kg of water vapor at 30°c and 100 kpa total pressure. determine (a) the specific humidity(b) the relative humidity (c) the specific enthalpy of the mixture in the tank as (kj/kg-mixture) (calculate by hand)(d) the specific enthalpy of the mixture in the tank as (kj/kg-dry air) (calculate by hand)(e) explain (in 1-2 sentences) the difference between the values in c and d – which value agrees with the enthalpy value in the psychrometric chart at this condition?

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
