Jakob II Bernoulli (17 October 1759 in Basel – 3 July 1789 in Saint Petersburg), younger brother of Johann III Bernoulli.
 Having finished his literary studies, he was, according to custom, sent to Neuchâtel to learn French.
 On his return, he graduated in law.
 This study, however, did not check his hereditary taste for geometry.
 The early lessons which he had received from his father were continued by his uncle Daniel, and such was his progress that at the age of twenty-one he was called to undertake the duties of the chair of experimental physics, which his uncle’s advanced years rendered him unable to discharge.
 He afterwards accepted the situation of secretary to count de Brenner, which afforded him an opportunity of seeing Germany and Italy.
 In Italy, he formed a friendship with Lorgna, professor of mathematics at Verona, and one of the founders of the Società Italiana for the encouragement of the sciences.
 He was also made corresponding member of the royal society of Turin; and, while residing at Venice, he was, through the friendly representation of Nicolaus von Fuss, admitted into the academy of St Petersburg.
 In 1788, he was named one of its mathematical professors.
A propeller is a type of fan that transmits power by converting rotational motion into thrust.
 A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade.
 Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law.
 A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers – they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propeller's average of 0.6 and the ability to throw thrust in any direction at any time.
 Their disadvantages are higher mechanical complexity and higher cost.
A Bernoulli grip uses airflow to adhere to an object without physical contact.
 Such grippers rely on the Bernoulli airflow principle.
 A high velocity airstream has a low static pressure.
 With careful design the pressure in the high velocity airstream can be lower than atmospheric pressure.
 This can cause a net force on the object in the direction normal to the side with lower local pressure.
 A Bernoulli gripper takes advantage of this by maintaining a positive pressure at the gripper face compared to the ambient pressure, while maintaining an air gap between the gripper and the object being held.
A ducted fan is a propulsion arrangement whereby a mechanical fan, which is a type of propeller, is mounted within a cylindrical shroud or duct.
 The duct reduces losses in thrust from the tips of the props, and varying the cross-section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow according to Bernoulli's Principle.
 Ducted fan propulsion is used in aircraft, airships, airboats, hovercraft and fan packs.
Nicolaus II Bernoulli, a.k.a. Niklaus Bernoulli, Nikolaus Bernoulli, (6 February 1695, Basel, Switzerland – 31 July 1726, St. Petersburg, Russia) was a Swiss mathematician as were his father Johann Bernoulli and one of his brothers, Daniel Bernoulli.
 He was one of the many prominent mathematicians in the Bernoulli family.
Daniel Bernoulli FRS ( ; ] ; 8 February 1700 – 17 March 1782) was a Swiss mathematician and physicist and was one of the many prominent mathematicians in the Bernoulli family.
 He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics.
 His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy, which describes the mathematics of the mechanism underlying the operation of two important technologies of the 20th century: the carburetor and the airplane wing.
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
 The principle is named after Daniel Bernoulli who published it in his book "Hydrodynamica" in 1738.
An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a "<dfn >restriction plate</dfn> ").
 Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.
 It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid.
 When the velocity increases, the pressure decreases and vice versa.
Johann II Bernoulli (18 May 1710, Basel – 17 July 1790, Basel; also known as Jean) was the youngest of the three sons of Johann Bernoulli.
 He studied law and mathematics, and, after travelling in France, was for five years professor of eloquence in the university of his native city.
 In 1736 he was awarded the prize of the French Academy for his suggestive studies of aether.
 On the death of his father he succeeded him as professor of mathematics in the University of Basel.
 He was thrice a successful competitor for the prizes of the Academy of Sciences of Paris.
 His prize subjects were the capstan, the propagation of light, and the magnet.
 He enjoyed the friendship of P. L. M. de Maupertuis, who died under his roof while on his way to Berlin.
 He himself died in 1790.
 His two sons, Johann and Jakob, are the last noted mathematicians of the Bernoulli family.
In fluid dynamics the Borda–Carnot equation is an empirical description of the mechanical energy losses of the fluid due to a (sudden) flow expansion.
 It describes how the total head reduces due to the losses.
 This is in contrast with Bernoulli's principle for dissipationless flow (without irreversible losses), where the total head is a constant along a streamline.
 The equation is named after Jean-Charles de Borda (1733–1799) and Lazare Carnot (1753–1823).
