The temperature at the beginning of the compression process of an air-standard otto cycle with a compression ratio of 8 is 540°r, the pressure is 1 atm, and the cylinder volume is 0.02 ft'. the maximum temperature during the cycle is 3600°r. determine (a) the temperature and pressure at the end of each process of the cycle. (b) the thermal efficiency, and (e) the mean effective pressure, in atm.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
