Extruder barrel diameter 4.5 in and length 11ft. the extruder screw rotates at 60 rev/min and its channel depth 0.35 in and flight angle 20°. the plastic melt has a shear viscosity 125x10^-4 lb-sec/in^2. determine the following a)- qmax and pmax. b)- the shape factor for a circular die opening with diameter 0.312in and length 0.75 in c)-the value of q and p at the operating point.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
