Estimate the steady-state flux of atomic hydrogen at 25 °c through a steel vessel of wall thickness 4 mm given that its inside surface is kept saturated with hydrogen at a concentration of 4.2 moles m ; the outside surface is exposed to the atmosphere. the diffusivity of hydrogen in a-iron is d. = 0.1 mm ? s? , q = 13.4 kj mol? . if the vessel contains 20 moles of hydrogen, estimate the hours taken to dissipate all of the hydrogen given that the vessel has a surface area of 2m². comment on why it is possible to store hydrogen gas in iron cylinders for much longer periods. how does dissolved hydrogen affect the mechanical properties of a-iron?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)
