A gear train has two gears. The driver gear has 8 teeth and a diametral pitch of 6 teeth/inch. the follower gear has 24 teeth. What is the diametral pitch of the follower gear?

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

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

On solidification from a melt, the polymer polyethylene forms a semi-crystalline spherulite structure. (i) sketch an individual spherulite and label the amorphous and crystalline regions. (ii) draw a schematic to show the changes in specific volume with temperature during cooling from the melt, comparing it to the theoretical extremes of fully crystalline and fully amorphous (indicate tm and tg)
