1 The radicas of the cylindecical rock core is 1cm, the length
is 5cm, and the viscosity of the oil is impa. s. The pressure
difference between the two ends of the rock core is 0.2
atmospheric pressure and we get 15 cm oil from the outlet
in 2 minutes, Please find permeability of the rock core

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
