Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
Two of the factors utilized are widely considered to be dummies as their value and thus their impact upon the formula typically is 0. [2] When using an O-score to evaluate the probability of company’s failure, then exp(O-score) is divided by 1 + exp(O-score). [3] The calculation for Ohlson O-score appears below: [4]
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.
Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water.The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution.
Volumetric flow rate is defined by the limit [3] = ˙ = =, that is, the flow of volume of fluid V through a surface per unit time t.. Since this is only the time derivative of volume, a scalar quantity, the volumetric flow rate is also a scalar quantity.
The angle associated with a complex number (+) is given by: Thus, in equation 4, the angle associated with the product is: + Note that this is the same expression as occurs in equation 3.
The Patent Prosecution Highway (PPH) is a set of initiatives for providing accelerated patent prosecution procedures by sharing information between some patent offices. [1] It also permits each participating patent office to benefit from the work previously done by the other patent office, with the goal of reducing examination workload and ...
Baden Powell II was born at Stamford Hill, Hackney in London. [2] His father, Baden Powell I (1767–1841), of Langton and Speldhurst in Kent, was a wine merchant, [2] who served as High Sheriff of Kent in 1831, and as Master of the Worshipful Company of Mercers in 1822. [3]
