The usaf is thinking of purchasing a improved automatic controller (no human required) at a cost of $100,000 that can make 4,000 target contacts per hour to replace usaf specialists that can, on average, make 1,000 target contacts per hour. note that a usaf specialist is paid a relatively low salary of $8/hour (but with good veteran benefits) and that the controller will require $1/hour maintenance costs. how many hours of target detection would it take to pay off this new controller?

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
