Afirm is considering either leasing or buying a microcomputer system. if purchased, the initial cost will be $250,000; annual operating and maintenance cost will be $75,000 per year. based on a 6-year planning horizon, it is anticipated the computer will have a salvage value of $15,000 at that time. if the computer is leased, the firm will owe $50,000 at the beginning of each year. in addition, annual operating and maintenance costs in excess of the annual lease payment will be $80,000 per year. you are to draw the cash flow diagrams for the buy option and one for the lease option • state any assumptions (if any) clearly.

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
