Consider slug or plug flow past a long flat, isothermal plate that is aligned with the flow. the temperature of the fluid far from the plate is. consider the plate to be at a constant temperature that is hotter than the free steam. + show the idealizations, the energy transport equation for these circumstances can be reduced

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?
