- W2155337564 abstract "A slit die of variable height H (0.135 in., 0.1975 in., or 0.2488 in.) width W 2.5 in., and variable length Le (12.0 in., 12.5 in., or 13.5 in.) has been designed and constructed for measuring the wall shear stress σw and the hole pressure error PH. Values of PH and σw are obtained directly and rapidly on a chart recorder from three commercial pressure transducers by means of an electronic differencing technique. The reliability of PH measurements is established by the excellent agreement between viscosity η values obtained from this apparatus and a rheogoniometer and by measuring negligible values of PH for the New tonian fluid, glycerine, for σw 0 for σw ≥ 800 dyn/cm2 and values of PH < 0 for a low-elasticity solution of polystyrene in dioctyl phthalate (DOP). Values of PH are found to be independent of the distance E of the transducers from the die exit and the die height which indicated that PH is independent of the undisturbed wall pressure Pw for constant values of σw. Our values agree well with those measured by Higashitani for a similar Separan solution in a different slit die. Using this new slit die, it is shown the PH is sensitive to changes in molecular weight (MW) for a series of solutions of polystyrene in DOP and that PH could be used to monitor continuously the changes in molecular structure which occured during the mechanical degradation of a 2.0% aqueous poly(ethylene oxide) solution. The simple relation between PH and N1 (PH = −cN1, where c is a constant) is verified for solutions of polystyrene in DOP and aqueous Separan solutions over a large range of flow conditions (⋅ = 1000 sec−1). Because c is found to vary slightly with polymer type, concentration, and molecular weight, a method is presented for obtaining N1 directly from PH data." @default.
