What horsepower must be supplied to the water to pump 3 cfs at 68°F from the lower to the upper reservoir? Assume that the head loss in the pipe is given by hL=0.018(L/D)*(V2/2*g) where L is the length of pipe, D is dimeter of the pipe and V is velocity in the pipe. Moreover, there is sudden-expansion head loss in the system that can be calculated by V2/2*g. Sketch HGL and EGL. (20 pts)

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
