Monazite is a Ce phosphate mineral that commonly contains abundant rare earth elements (REE), metals that have many high-tech applications. Economically viable lag deposits of monazite can occur in some sandstone. You’ve been hired to evaluate a potential deposit. On a relatively level ground surface in the desert, the outcrop width (measured perpendicular to strike) of a monazite-bearing sandstone unit is 23 m. The sandstone has an orientation of 308, 32 (strike, dip), as measured in outcrop. In this area,...

(a) A horizontal pipe of diameter 10 cm carries crude oil from A to C as shown in Figure 4. At a point B, midway between A and C, oil leaks at a volume flow rate of QL . The pressure drop per unit length along AB is 640 Pa/m and along BC is 600 Pa/m. Determine the leakage flow rate QL . The density of oil is 800 kg/m3 and its dynamic viscosity is 0.1 N.s/ m2 . You...
(c) The structure shown in Fig Qlc is a plane pin-jointed structure made from identical Aluminium tubes 2m in length having an axial stiffness of 8MN/m and subject to a point load as shown. Fig Qlc 2 m Show on a sketch how the structure can be modelled exploiting the vertical axis of symmetry. For the symmetry model, indicate all restraints and loads, set up a system stiffiness matrix and indicate the active and inactive degrees of freedom. There is...
1) An observer fails to check the bubble of a level and it is off two divisions on a 100-m sight. If the sensitivity of the bubble is 20-sec, what error would there be in the reading? 2 ) The following azimuths are from the north: 329°20’, 180°35’, 48°32’, 170°30’, 145°25’, 319°35’, 350°45’, 95°49’, 11°30’, 235°45’. Express these directions as (a) azimuth from the south, (b) back azimuths, (c) bearings. 8) 6.7 The following azimuths are reckoned from the north:...
