(Drag—low Reynolds number) (a) How fast do small water droplets of 0.06-µm (6 × 10-8 m) diameter fall through the air under standard sea-level conditions? Assume the drops do not evaporate. (b) Repeat the problem for standard conditions at 7000-m altitude.

On a average work day more than work place firs are reorted

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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
