The following data represent the maximum wind speed (in knots) and atmospheric pressure (in millibars) for a random sample of 20 hurricanes that originated over the Atlantic Ocean in the last decade. Use this data to construct a model for the speed of an Atlantic hurricane, using barometric pressure as a predictor.

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

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

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
