Asked to find volumetric flow rate of gas - what equation could you use? Correct Answer: PV=mRT - Pv=RT - V(rate) = m(rate)*R*T/P====remember v=V(rate)/m(rate) How do you calculate feet of air from inches of H20? Correct Answer: Convert inches of H20 to feet of H20 and then multiply by (density water/density air) - counterintuitive. What is a good way of manipulating the equation for velocity through a pitot tube in handbook? Correct Answer: v=(2g(p0-p1/y))^1/2 can be changed to v= (2gh)1...

This document is a set of class notes covering week 3 of thermodynamics at OSU. It has examples and practice problems covering carnot cycles, entropy changes, reversible and irreversible processes, and more.

Its describing about heat engine and carnot cycle

This document includes content covering the various ideal and actual power cycles such as steam cycles, carnot cycle, rankine cycle, brayton cycle, joule cycle, as well as combined cycles that allow for regeneration, cogeneration, and reheating. The notes cover the general and detailed types of engine cycles such as a two stroke and four stroke engine cycles along with the processes occurring. Most cycles include methods to calculate the thermal efficiency, turbine efficiency, work output, heat ...
