WebAug 28, 2024 · Number average of molecular weight is the total weight of polymer, 2.2.5, divided by the number of polymer molecules, 2.2.6 . The number average molecular weight (M n) is given by 2.2.7 , where M i is molecular weight of a molecule of oligomer n, and N i … WebSep 28, 2024 · Correlating Melt Flow Index to Molecular Weight The certificate of analysis for polymer resins often includes a melt flow index (MFI) or melt flow rate (MFR), reported as grams of material/10 min under a specified temperature and load. This testing is normally performed per ASTM D1238 or ISO 1133 using a plastometer.

WebThe formula to convert from milliwatts to kilowatts is: kilowatts = milliwatts ÷ 1,000,000 Conversion Example Next, let's look at an example showing the work and calculations that are involved in converting from milliwatts to kilowatts (mW to kW). Milliwatt to Kilowatt Conversion Example WebAssume a power coefficient of 0.36. Round off your answer to a whole number (no decimals) and do not include the unit. Using the equation: P= 0.5 * air density * Pie *R^2 * V^3*Cp CP= in MW air density is 1.3 kg/m^3 not 1.22. What is, in MW, the power generated by a turbine that has a power coefficient equal to 0.24 when the wind speed is 10.3 ...
WebFormula and Molecular Weights. The formula weight of a substance is the sum of the atomic weights of each atom in its chemical formula. For example, water (H 2 O) has a formula weight of: 2 × (1.0079 amu) + 1 × (15.9994 amu) = 18.01528 amu. If a substance exists as discrete molecules (as with atoms that are chemically bonded together) then ... WebThe watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. It is used to quantify the rate of energy transfer.The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his …
WebMn is the number averaged MW, and Mw is the weight averaged MW. The midpoint of the distribution in terms of the number of molecules is Mw. The third moment, Mz, has more weighting with regards to higher MWs. The Mw:Mn ratio is termed as polydispersity, and … WebThe molarity calculator equation The Tocris molarity calculator is based on the following equation: Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol) An example of a molarity calculation using the Tocris molarity calculator
Webϒ g is the gas gravity (MW g /MW air), dimensionless (to be discussed) ϒ o is the oil specific gravity (ρ o /ρ w), dimensionless; T is the temperature, °F; These equations are valid below and up to and including the bubble-point pressure. Therefore, we can use these equations to generate B ob for Equation 3.43b if it is unavailable from ...
