An air-standard otto cycle has a compression ratio of 8 and temperature and pressure at the beginning of the compression process are 560°r and 14.7 lbf/in2 respectively. the heat addition per unit mass of air is 400 btu/lb. determine the (a) maximum temperature, in 'r (b) maximum pressure, in lbfin (c) heat rejected, in btu/lb (d) thermal efficiency 10 pts] [10 pts] 10 pts 10 pts) solve the problem using the cold-air standard assumption using cv 0.172 btu/lb. r and k 14

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form
