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

Purpose: The purpose of this experiment is to understand data analysis through measuring and calculating different values. These values include length, diameter, circumference, volume, and the percent error. Introduction: This experiment helps students understand data analysis such as units, conversions, error types and calculation, accuracy, and precision by requiring the students to measure a pipe using calipers, string, and a meter stick. This also teaches about uncertainty in measurement and

detection of sound have the same effect on the experimental line of best fit as the inaccurate measurement of resonance point since they are both random errors. A way to increase accuracy would be to use a decibel meter to measure where the resonance (volume) is greatest. Another way to increase accuracy would be to also perform more

record it in grams (g). Fill a graduated cylinder with water to ~50mL, and record the exact measurement. Place the metal sample in the graduated cylinder. Record the new measurement and subtract the original from it to get the volume. Record that as well. Divide the mass by the volume, and finally record that number as your density. Next, test the magnetism. Do so by placing a magnet next to the metal and observing if there is a pull. Finally, to test the specific heat, place the metal into a test tube
