A pipeline is needed to transport medium fuel oil at 77 oF. The pipeline needs to travers 80 mi in total, and the initial proposal is to space pumping station 2 miles apart. The line needs to carry 750 gal/min and would be made of 6-inch schedule 80 steel pipe. Calculate the pressure drop between stations and the power required to maintain the same pressure at the inlet of each pump. Comment on the design.

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
