Practice Problems (12 points) A chemist has designed a reaction to create carbon dioxide (CO2). They have combined 12 lbm of carbon (C), 24 lbm of oxygen (O2) and created 22 lbm of Carbon dioxide, and an unknown about of carbon monoxide (CO). Figure out the mass [lbm] of carbon monoxide created. Write out the balanced chemical equation for this reaction on a lbmol basis (i.e. ____ C + ___ O2 ___ CO2 + ___ CO) A chemical reactor tank has three inlets, and two outlets. The diameters if the inlet/out pipes is: Inlet 1 is 0.020 m Inlet 2 is 0.050 m Inlet 3 is 0.015 m Outlet 1 is 0.015 m Outlet 2 is 0.085 m The mass flow rates of each inlet are: Inlet 1: 0.51 kg/min Inlet 2: 0.75 kg/min Inlet 3: 0.011 kg/min Simultaneous with the above inlet conditions, the outlets have mass flow rates of: Outlet 1: 0.35 kg/min Outlet 2: 0.67 kg/min Calculate the net rate of accumulation (positive or negative) of chemicals in the reactor tank. Your answer should be in units of kg/min. A system consists of a mixture of 2.00 ft3 of a liquid having a density of 50.0 lbm/ft3 and 4.00 lbm of a second liquid having a specific volume of 0.0400 ft3/lbm. What is the specific volume of the mixture? Preparatory Reading Questions (2 points) Sketch the phase diagram for water. Label the triple point, vaporization curve, sublimation curve, fusion curve, and critical point. Identify the following regions: solid, liquid, supercritical fluid, vapor, and gas. Is quality a property? How is it used in specific volume, specific internal energy, and specific enthalpy calculations?
