Acentrifugal pump is used to transport water through a l-inch schedule 40 commercial steel pipe a distance of 250 m and delivers the water to an open storage vessel 20 m above the inlet. both the inlet and outlet are at ambient pressure. the pump has a performance curve given by the expression: hsupply = ao + aj v + a2 v2 + a3 v + a4 v4, with ao = 130.0, aj +0.1371, a2 = -0.3920, a3 = 0.04047, a4 - -0.002058, with h given in feet and v given in gpm. the pipeline includes 5 threaded smooth elbows, one fully open globe valve, and one fully open gate valve. determine the flow rate. show your work.

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?

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
