Unformatted text preview: -unbalanced net force up-F bolts +ma net upward force=(pi)r^2(p)-Force up from gas=force of weight, bolt, and atm (if nothing is happening)-process classification: batch or semi-batch (both with chem. rXns) or continuous-normally steady state-Residence time: RsT=(Vm 3) /(V rate m 3 /s) or v/V rate is reasonance time-gen mat bal: (input-output) + (production-consumptio) +accumulation-not pro/consum only for chem. Rxn’s and accumulation only for steady steady-MAT BALANCES:-draw pics and write down all info always!!!-Examples:-Find V in 1 st order reaction (A to B) given concentrations of A in and out, flow rate of A(same for in and out), and given rate constant conc in (flowrate)=conc out (flowrate) + rateconstant(conc out )(volume) -...
