Steam at 200psi and 600 of (state 1) enters a turbine through a 3-inch-diameter pipe with a velocity of 10 ft/s. the exhaust from the turbine is carried through a 10-inch-diameter piper and is at 5 psi and 200 of (state 2). assume no heat exchange at the turbine, what is the power output of the turbine? the following state functions are given: h1=1322.6 btu/lbm, h2= 1148.6 btu/lbm, v1= 3.058 ft3/lbm, v2= 78.14 ft3/lbm.

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
