Volume Three

Comparing the volumes of a round and square donut. Which of these two donuts better fits in a dozen box? Christina Tannous Supervisor: Mr. Omar Rachmani January 25, 2015 Everybody loves to have a donut every once in a while. It’s a tasty desert that nobody can deny; children all the way to adults love it. I am personally a huge donut lover! When I usually walk through the mall I find different coffee shops selling square donuts, and not only round ones. This is what sparked the idea in my

.PROCESS PLANNING 1.1 PURPOSE OF PROCESS PLANNING Process planning is defined as the development of set of instructions describing all the operations required to convert a design into a product. Process planning deals with the selection of the processes and the determination of requirements of the processes. The selected operations and requirements have to be realized in order to transform raw material into a given shape. All the specifications and requirements of operations are included in the

are able to identify the unknown liquid and unknown solid that we are given. In order to get the density of a liquid we are first going to divide the mass of the liquid by the volume of the liquid in order to get us the density. In order to get the density of a solid we are going to divide the mass of the solid by the volume of the solid in order to get us the density of the solid. Next we are going to want to find the boiling point of a liquid we find this by placing a thermometer and test tube into

Water Hammer | Plumbing Sugar Land Water hammer, also called hydraulic shock, occurs when water stops suddenly after a faucet is quickly turned on or off. The sudden stop of running water causes the loud banging characteristic of water hammer in a home’s plumbing in Sugar Land. When it occurs suddenly having never happened before, it indicates there is a problem in the home’s pipes. Water hammer is not a benign condition; the causes of water hammer requires repair to prevent damage to a home’s plumbing

learn how to measure mass and volume and to determine the density of water, alcohol, and a solid. We will be using a laboratory scale or balance and the graduated cylinder to determine the density of water and of alcohol. First, place an empty graduated cylinder on a balance, determine its mass and record the value under the Density of Water: Data Table. Next, pour 25 mL of tap water into the graduated cylinder. Place the cylinder on the lab bench and read the volume of the water using the bottom

where r0 is the external radius of the pellet, np the number of pellets per unit reactor volume, Mw and ρ are the molecular weight and 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)

Molar Volume Lab Report  Objective: To find the molar volume of hydrogen gas at STP. Materials: Mg ribbon, thermometer, barometer, 6M HCL, eudiometer(Acid), 50 ml beaker, 400 ml beaker, cotton thread, base #7, pipet, ring stand, buret clamp, funnel, cork(hole through center vertically), cylinder full of water Procedure: The eudiometers was clamped onto the buret clamp on the ring stand. The mass of the Mg ribbon was recorded and was the bent to form a circle. A 15.0 cm long cotton thread was then

shape on the ratio of surface area to volume. Complete the following exercises. Part 1 Let’s investigate how size influences surface are to volume ratios. Let’s assume we have a cube with a volume of 1cm3. Each side of the block equals 1cm. Picture a die for each cube. 1. How many sides does a cube have? 2. Let’s use 1 block to represent a small cubed organism and 8 blocks to construct a large cubed organism. Complete the following table. Total Volume Total surface area Surface area:volume

area to volume ratio on the rate of diffusion is investigated. Four agars containing phenolphthalein, an indicator that turns colorless in acid, each ranging in size were used. In this experiment, the agar cubes represent cells and the time it took for cubes to turn colorless shows the rate of diffusion. Next, the cubes were placed in a beaker and just enough hydrochloric acid was added to cover them. Then, the time it took them to turn colorless was measured. It was observed that when volume increases
