Follow the steps of the Systematic Approach of Section 14.4—that is, (1) identify the system, (2) determine whether the process is batch or rate, (3) construct a schematic diagram with inputs and outputs, (4) Label known material quantities or rates of flow and so on.
A brine solution is 20.0% salt and has 70.0 kg of water evaporated per hour. To produce 195 kg of pure salt (0% moisture) per day, how long should the process operate each day and how much brine must be fed to the evaporator per hour?
Someone leaves a 100-W light bulb on before leaving and sealing up a 2 m x 4 m x 4 m room full of air. Initially the air temperature is 20oC, and the air pressure is 100 kPa. Assuming that the mass of the air in the room stays constant and ignoring any pressure changes
(a) determine the temperature of the air in the room after 8 hours. (b) What would the temperature of the room be after 8 hours if someone had also left a 50-W fan operating in the room at the same time? Given: Air; L = 4m; W = 4m; H = 2m; T1 = 20oC = 293 K; W?=?0.1 kW; P = 100 kPa; t = 8 hours Assume: Q = 0 (insulated); ?KE = ?PE = 0 Air behaves as an ideal gas with constant specific heats: cv = 0.718 kJ/kg-K R = 0.287 kJ/kg-K P = constant; m = constant What will be an ideal response?
