Question:
How many kilograms of methane (CH4) are in perfectly insulated piston with the following properties:
Volume = 2 cubic meters. Pressure = 3 bar absolute. Temperature = 50 Celcius?
The ideal gas law constant R = 0.00008314 cubic meters.bar/K/gmol.
Assume methane is an ideal gas.
Tris (pentafluorophenyl) borane, commonly known by its acronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound.
What is the maximum work ( in Btu/lb) obtainable from an adiabatic expansion of ethylene gas through a turbine from 1000 psi and 340 F to a pressure of 100 psi.
