Afirst order reaction is employed in a destruction kind of a
certain kind of microorganism. ozone is used as the disinfectant
and the reaction is found to be
dc/dt=-kc. where c is the concentration of microorganisms,
microbes/ml. k is the rate constant, and t is time, min.
the present system employs a completely mixed flow reactor and
there is some sort of baffling it to create a series of cmf
reactors.
a. if the objective is to increase the percentage microorganisms
destruction from 80% to 95%, how many cmf reactors are needed in
the series?

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
