Nitrogen gas at atmospheric pressure and a bulk inlet temperature of 27 degree c is heated in a 2.5 cm inner diameter tube having a constant surface temperature of 100 degree c. the bulk average velocity is 1.2m/s and the tube is 1.5m long. determine the net heat transfer rate to the nitrogen, qconvection

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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
