the density of the reactive solid, respectively. Under the above assumptions (a-e), the mass balances for a steady-state counter current moving bed reactor can be stated as: u_g (dX_1)/dz+n_p R_1 (X_1,X_s )=0 (6) u_g (dX_2)/dz+n_p R_2 (X_2,X_s )=0 (7) u_s (dX_s)/dz+n_p (R_1 (X_1,X_s )+R_2 (X_2,X_s ))=0 (8) Where ug and us are the gas and solid velocities in reduction zone and Ri is reaction rate per pellet, respectively. The energy balances

heavier, it will sink. The force of buoyancy is important in many different areas, and especially in the making of ships. The surface area that is touching the water of the ship is very large, due to the shape of the hull, and that, beside the density of the ship, is what keeps the ship

General Chemistry 1 Lab 1: Laboratory Techniques and Measurements Purpose: The purpose of this lab is to ensure that students are able to understand how to conduct measurements of length, mass, temperature, density and volume using different measuring devices. Students will also learn how to dilute substances by using simple algebra. Procedure: 1. Prepare a data table similar to Data Table 1 shown below. 2. Choose any three objects that are shorter than the metric ruler to measure, such

immersed object. If the force of the liquid on the object is greater than that of the object on the liquid then the object will float. In other words buoyancy is dependent upon the density of the liquid and the volume of the object submerged. Buoyancy: Fb= d*g*V Where Fb= the magnitude of the buoyant force d= density of the liquid, g= force of gravity (9.8 m/s^2), V= volume of the submerged object All object displace fluid when in a liquid,

protect is valuable – A/F, STL Reduces the fracture through strengthening – P, STL I like the bone density mention. It’s important to increase bone density to strengthen and protect bones – NT, STL It’s proven to do what I need it to do. Gives me great confidence, reading that – P, NJ It’s proven to help. I like the word “proven” – makes it seem scientifically tested – DH, ATL I’d consider Prolia if my density was not improving, seeing that it has been proven to work on others – A/F, NJ I like the word

Introduction A lava lamp (or Astro lamp) is a decorative novelty item, invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava, hence the name. The lamps are designed in a variety of styles and colours. The underlying fluid mechanics phenomenon

exercise is learning how to use a micropipette to find the density of different liquids, and be able to identify an unknown liquid using density. Also, learn how to evaluate the experimental accuracy, precise, and error of small volumes used in biochemistry based on the theory that 1gram of water at room temperature equal 1millimeter (#1 Bruice). If the density of water that determined after the experiment

The Density Den (Experiment 4.3) Taken from Obook (aim, materials and method) Date: Monday 15th June Partners: Nicole and Grace Introduction: - When people think of Archimedes they often think of the famous tale of his bath, and how he helped discover density whilst unknowingly using the displacement method. - Density is the mass and volume of substances which is different in the 3 states of matter. The density of the 3 matters can often be affiliated with the amount of space in-between the particles

Using a volumetric pipet, graduated cylinder, and a beaker will yield different accuracies, due to the nature of the glassware. Thus, as mentioned before, it is important to understand when to know that one’s data is reliable or not. The formula “density = mass/volume”

Purpose: The lab was performed for the purpose of calculating the density of each type of object and determining if calculating the volume, and therefore the density, of two cubes can be more effectively done with a ruler (through the direct method) or by water displacement. Materials: 1 Scale 1 Rock 2 Corks 2 Aluminum Cubes 4 Paper clips 2 Marbles 1 50 mL graduated cylinder 1 25 mL graduated cylinder 1 Calculator 1 Ruler Procedure: 1. Weigh and record the mass of each pair of objects (only use
