Sketch a streamline, pathline, and streakline
For a given flow the velocity from time t=0 to t=5s was u=2 m/s, v=0. Then from t=5s to t=10s the velocity was u=+3 m/s, v=-4 m/s. A dye streak was started at t=0, and a path was traced from that same point at the same time. Draw to scale the streakline, pathline, and streamlines at t=10s. Please solve and explain.
Name three types of metamorphic foliations, and draw a small sketch that shows a situation. Where a metamorphic foliation could cause problems in an excavation.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
A sewage treatment works (STW) with 4 single-stage trickling filters has become organically overloaded due to the discharge of a biodegradable industrial effluent to the STW. This is causing effluent to pond on the surface of the filters.
