Multistep soda and lime are added to glass batch in the form of soda ash (na2co3) and limestone (caco3). during heating, these two ingredients decompose to give off carbon dioxide (co2), the resulting products being soda and lime. compute the weight of soda ash and limestone that must be added to 170 lbm of quartz (sio2) to yield a glass of composition 74 wt% sio2, 19 wt% na20, and 7 wt% cao. part 1 you are to compute the weight (in lbm) of soda ash and limestone that must be added to a certain amount of quartz to produce a particular glass composition. first, compute the lbm of both na2o and cao that is necessary for the particular glass composition that is given in the problem. what is the weight in lbm of: (a) na2o lbm (b) cao lbm click if you would like to show work for this question: open show work

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
