Consider an oil well drilled to a depth of 1000 ft and connected to the surface 3 with 4-in (internal diameter) new commercial steel pipe. if the pressure in the well reservoir is a constant 500 psig, what is the expected flow rate of liquid oil (in barrels per day) at the surface if the surface pipe is open to atmosphere? assume 1000 ft of equivalent pipe and no gas flow with the oil. the specific gravity of the oil is 0.93, and its viscosity is 0.4 centipoise. an oil barrel is 42 gal. make sure that you clearly state and justify any assumptions.

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
