A100 -l tank is filled with pure water when an inflow pipe is opened and a sugar solution with a concentration of 20 g/l flows into the tank at a rate of 0.1 l/min. the solution is thoroughly mixed and flows out of the tank at a rate of 0.1 l/min. (a) find the mass of sugar in the tank at all times after the inflow pipe is opened. (b) what is the steady-state mass of sugar in the tank? (c) at what time does the mass of sugar reach 95 % of its steady-state level?

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?
