The diameter of an extruder barrel = 85 mm and its length = 2.00 m. the screw rotates at 55 rev/min, its channel depth = 8.0 mm, and its flight angle = 18°. head pressure at the die end of the barrel = 10.0(106) pa. viscosity of the polymer melt = 100 pa- s. find the volume flow rate of plastic at the die end of the barrel.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
