(Ans: 2.71 KJmol –1). Doctors measure body mass index (BMI) and waist circumference to screen and diagnose overweight and obesity. Obesity is a serious medical condition that can cause complications such as metabolic syndrome, high blood pressure, atherosclerosis, heart disease, diabetes, high blood cholesterol, cancers and sleep disorders. Example: Sam does an experiment to find how long it takes an apple to drop 2 meters. The theoretical value (using physics formulas) is 0.64 seconds.. But Sam measures 0.62 seconds, which is an approximate value. Sep 16, 2020 · Heart failure is a condition in which the heart is no longer able to pump oxygen-rich blood to the rest of the body efficiently. This causes fluid to build up in your body. Limiting how much you drink Useful Calculations. Want to know how much moisture is in compressed air? Or the cost of pressure drop? These and other application questions can be answered with these easy-to-use calculators. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers. potential. Each potential refers to the same point in the solution, and each component is additive algebraically according to whether it increases (positive) or decreases (negative) the Yw at that point. The increase or decrease is always relative to pure water at atmospheric pressure, at the same temperature as the solution (see Chap. 1). The vertical pressure at wetting for the specimen is chosen equal to the vertical in-situ stress (overburden stress plus structural stress, if any) corresponding to the sampling depth. The test result indicates the amount of heave or hydrocompression that can result when the soil at a given fill depth is wetted from the current moisture ... Osmotic pressure by definition means the pressure required to stop the solvent (pure) completely from passing into a solution (impure) by osmosis through a semipermeable membrane. Osmotic pressure arises when a pure solvent is separated by a semipermeable membrane (which allows the solvent to move through it) from a solution containing a solute ... increase the water pressure in the section of the building near-est that alarm box. How does this pressure change assist fi re-fi ghters who must battle the blaze? PROBLEMS 1. The particle density of standard atmospheric air at 273.15 K (0 °C) is 2.687 3 1025 particles/m. Using the ideal gas law, calculate the pressure of this air. 2. Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension). Potential difference in volts. Calculate the resistance of the bulb when the potential difference is 8 V. potential difference = current × resistance . 𝑉𝑉= 𝐼𝐼 𝑅𝑅 • potential difference, in volts, V • current, in amps, A • resistance, in ohms, Ω 17. A kettle has a power rating of 2 kW. The exact volumes are not easily measured, so they are often estimated based on what we know about stroke volume and the factors that it affects such as blood pressure which we can measure. The equation for cardiac output is: HR x SV = Q. Therefore to calculate Q we must first establish HR and SV. An example at rest is shown below. • PilPotential vortiiicity if dih ilis often expressed in the potential vortiiicity unit (PVU), where 1 PVU = 10 −6 K kg − 1 m 2 s − . • Potential vorticity is always in some sense a measure of the ratio ofis always in some sense a measure of the ratio of Oct 16, 2017 · You can calculate these costs based on what you’re already paying your employees.

Limiting how much you drink Standard physics laws of temperature and pressure are used to measure the explosive potential of boilers and pressure vessels. New calculations show, for instance, that if liberated in a rupture, a 30-gallon hot-water tank at 90 psig (or 104.7 psia) has approximately 314,095 foot-pounds of energy to flash its water into steam at 332°F. When it is the pressure or potential which vanishes, then the boundary is often said to be free. Rigid and free boundaries reflect waves with unit magnitude reflection coefficients. A goal here is to establish fundamental mathematical properties of waves in layers while minimizing specialization to any particular physical type of waves. Calculating the percentage change in height from the wet soil to the dry will give you a measure of the swell factor of the soil. For example, if the dry soil was 1 inch high and the wet soil is 1.54 inches high, divide 1 by 1.54 and multiply by 100 to get a 65 percent swell factor.
