Using the vapor pressure-temperature relationships for caf2(α), caf2(β), and liquid caf2, calculate:

a: the temperatures and pressures of the triple points for the equilibria caf2(α) - caf2(β) - caf2(v) and caf2(β) - caf2(l) - caf2(v)

b: the normal boiling temperature of caf2

c: the molar latent heat of the transformation caf2(α)-> caf2(β)

d: the molar latent heat of melting of caf2(β)

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Fluids at rest possess no flow energy. a)- true b)- false

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
