Perform a simulation investigating three special processes - isobaric (constant pressure), isochoric (constant volume), and isothermal (constant temperature)
Consider n infinitely long hollow conducting tube tht is split in half with each half held at the indicated potential.
By applying a pressure of 200 atm, you can compress water to 99% of its usual volume. Sketch this process on a PV diagram, and estimate the work
A Joule cycle consists of two adiabats and two isobars: 1--> 2 and 3 ---> 4 are adiabatic compression and expansion respectively; 2 ---> 3 and 4 --->1
A supply of geothermal hot water is to be used as the energy source in an ideal Rankine cycle, with R-134a as the cycle working fluid. (See the diagrams below)
