The flow meter installed in the piping system measures the mass flow rate. Assume that the flow meter has a 0.5-in-diameter, square-edged orifice plate is used to meter the steady flow of 16C water through a 1.0-in pipe. Flange taps are used and the pressure drop measured is 50 cm Hg. Determine the air volume flow rate through the piping system. The specific gravity of mercury is 13.5.

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
