2. other igneous rock forms from lava that cools quickly on earth’s surface. classify the rock as either intrusive or extrusive, and identify another word used to describe this type of rock.

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

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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
