Apelton wheel nozzle, for which the coefficient of velocity is 0.95, is 330m below the water surface of a reservoir. the jet diameter is 100mm, the pipe diameter is 0.5m, it's length is 2km and f=0.01. the bucket deflects the jet through 160 degrees and they run at 0.46 times jet speed, bucket friction reducing the relative velocity at the outlet by 15% of the relative velocity at inlet. the mechanical efficiency of the turbine is 92%. find the flow rate and shaft power developed by the turbine.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

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
