Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?

Oxygen at 300 kpa and 400 k is in a closed system with an initial volume of 0.1 m3. is now compressed in a polytropic process, with exponent of n 1.2, to a temperature of 500 k. calculate: a) the boundary work done during the compression, in kj b) the heat transfer during the compression, in kj

Consider the transfer function for a first-order system g(s)=12(s+7)/(s^2+2s+9) for this system determine: a) poles and zeros of the function, b) the natural frequency and damping ratio, c) the peak value achieved in response to a unit step input, d) the peak time for a unit step input, e) the steady-state system response to a unit step input
