a) To bring your methane (CH4) to market you have to compress it to a pressure of 1 MPa. You are producing methane from a reservoir at a rate of 2 kg/sec and a pressure and temperature of 0.4MPA and 280K. This methane is run through an adiabatic compressor to bring it up to a pressure of 1 MPa. Using the appropriate balance equations and the chart given, find the minimum amount of power (work per time) required to compress the methane. b) To put methane on a ship for export, the methane needs to be liquefied. This is done by compressing and cooling a methane stream to P = 10MPA and T = 200K. It is then run through a choke valve operating adiabatically with an outlet pressure of P = 0.1 MPa. If the upstream methane stream consists of a mass flow rate of 10 kg/sec, using the appropriate balance equations and the attached chart, find rate at which liquid methane is produced downstream of the valve.

1.) A hand pump is used to inflate a bicycle tire to a gauge pressure of 70 psi. a) How much work must be done if each stroke of the pump is an adiabatic process and what is the final temperature of the gas? b) We inflate the tire in two steps: (i) an isobaric compression and (ii) an isochoric increase in temperature. Calculate the work done by gas/"us" and/or heat added/removed during the two steps! Is this a viable alternative to the adiabtic compression Explain! Atmospheric pressure is 1 atm, the air temperature is initially 25° C, and the volume of the air in the tire remains constant. Useful values: A bicycle tire is 26 in diameter and has a cross-sectional area of 2 in² [1 in = 2.54 cm]. 1 lb corresponds to a mass of 0.445 kg. c) For Take-Home only Solve the questions in a) and b) in terms of the initial pressure P₁ = P*, the final volume Vf = V* and the pressure ratio K = Pf/P*!
