1. A Little About Buoyancy o In order to understand how a boat can float in water we must first go over one of the principles behind such a feat: buoyancy. This principle in physics was discovered by the mathematician Archimedes about 2‚000 years ago‚ so it has been taught and understood for some time now. The basics of buoyancy involve the relationship between the weight of the object in question‚ in this case a boat‚ and the weight of the water it displaces. If the object weighs more than the

Figure 1 represents a typically layout used for fluidization. figure 1: Typical packed column set up used for fluidisation A packed column is constructed using a metal‚ glass‚ ceramic or plastic shell preferably with a corrosion resistant lining. The column should be mounted as vertical as possible to promote even liquid distribution. The packing material or bed

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

What is the distance from the top of the block to the water if the water is fresh? (a) density of fresh water is ρ_water = 1000 kg/m³ ΣF = 0 - (ρ_wood)g(V_wood) + (ρ_water)g(v_wood) = 0 (v_wood)/(V_wood) = (ρ_wood)/(ρ_water)
