An ideal gas Carnot cycle with air in a piston cylinder has a high temperature of 1200 K and a heat rejection at 400 K. During the heat addition the volume triples. Find the two specific heat transfers (q) in the cycle and the overall cycle effic
Write a computer program that plots the contour lines of (sigma(1), sigma(2)) on a 2d rectangular beam. Sigma represents the shear stress.
Two air flows are combined to a single flow. Flow one is 1 m3/s at 293 K and the other is 2 m3/s at 473K both at 1 bar. They mix without any heat transfer to produce an exit flow same as the flow one.
An initially empty canister of volume 0.2 m3 is filled with CO2 from a line at 800 kPa, 400 K. Assume the process runs until it stops by itself and it is adiabatic. Use constant heat capacity to find the final temperature in the canister.
