Using the ideal gas model find the final temp and mass of the air inside the cylinder for supply temperatures ranging from 300 to 500 k.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
