Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s. Note: 1 statute mile = 5,280 feet = 1,609 meters
MGD can be calculated from a measured incident air kerma at the top of the breast, , as follows: [4] D = K g c s {\displaystyle D=Kgcs} g {\displaystyle g} converts from incident air kerma to MGD, with a glandularity of 50%, based on breast thickness and HVL .
Million standard cubic feet per day is a unit of measurement for gases that is predominantly used in the United States.It is frequently abbreviated MMSCFD. MMSCFD is commonly used as a measure of natural gas, liquefied petroleum gas, compressed natural gas and other gases that are extracted, processed or transported in large quantities.
The conversion equations depend on the temperature at which the conversion is wanted (usually about 20 to 25 °C). At an ambient sea level atmospheric pressure of 1 atm (101.325 kPa or 1.01325 bar ), the general equation is:
MDCalc is a free online medical reference for healthcare professionals that provides point-of-care clinical decision-support tools, including medical calculators, scoring systems, and algorithms. [1]
For some usage examples, consider the conversion of 1 SCCM to kg/s of a gas of molecular weight , where is in kg/kmol. Furthermore, consider standard conditions of 101325 Pa and 273.15 K, and assume the gas is an ideal gas (i.e., =).
The metric equivalent flow factor (K v) is calculated using metric units: =, where, [3] K v is the flow factor (expressed in m 3 /h), Q is the flowrate (expressed in m 3 /h), SG is the specific gravity of the fluid (for water = 1),
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
