4.16A billet of PVC weighing 150 g is to be
compression moulded into a long-
playing record of diameter 300 mm. If
the maximum force which the press can
apply is 100 kN estimate the time
needed to fill the mould. The density
and viscosity of the PVC may be taken
as 1200 kg/m³ and 10 Pa s respectively.
