A 1cm thick plate of aluminum is reduced in thickness by cold rolling according to the in three steps: 0.7, 0.4, 0.2 cm. Compute the total strain on the basis of initial and final dimensions AND the summation of the incremental strains, using:a. engineering strainb. true strainc. how does this show an advantage for the use of true strain in metalworking?

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
