A 100 cm pipeline conveying crude oil will need to take a 60° turn from its right way to avoid a rock boulder. If the pressure intensity in the line is 12 bar and the flow rate is not more than 0.2 m3/s, estimate the forces that will be withstood by the concrete support to be provided at the bend. Density of crude oil is 800 kg/m3 while its viscosity is 0.95 Ns/m2.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

On solidification from a melt, the polymer polyethylene forms a semi-crystalline spherulite structure. (i) sketch an individual spherulite and label the amorphous and crystalline regions. (ii) draw a schematic to show the changes in specific volume with temperature during cooling from the melt, comparing it to the theoretical extremes of fully crystalline and fully amorphous (indicate tm and tg)
