Chapter 3 Pressure Measurement Examples Example 3.3 A special high pressure U tube manometer is constructed to measure pressure differential in air at 13.8 MPa and 20oC. When an oil having a specific gravity of 0.83 is used as the fluid‚ calculate the differential pressure in N/m2 that would be indicated by a 135 mm reading. p − pa = m g h( gc m − f ) = (0.83)(1000) = 830kg/m 3 = = p 13.8 × 10 6 = f a RT (287)(293) g h( m − f ) p − pa = gc = 9.81(0.135)(830 − 164.11) = 881.51N/m 2 Example

is also known as the figurate triangle‚ the combinatorial triangle‚ and the binomial triangle. Even though Pascal’s Triangle is named after seventeenth century mathematician‚ Blaise Pascal‚ several other mathematicians knew about and applied their knowledge of the triangle hundreds of years before the birth of Pascal in 1623. The Arabs‚ Persians and the Chinese discovered Pascal’s triangle in earlier centuries. The earliest depictions of a triangle of binomial coefficients occur in the tenth

Descartes vs. Pascal For centuries‚ human beings have been debating over the validity of the use of reason. This is a very‚ very difficult subject to discuss‚ as one is forced to study something which is at that moment being used in their study. Two classic thinkers who contrasted on their view of reason were Descartes and Pascal. Though both saw reason as the primary source of knowledge‚ they disagreed over the competence of human reason. Descartes‚ the skeptic‚ said that we could use reason

Blaise Pascal (1623-1662) France Pascal was an outstanding genius who studied geometry as a child. At the age of sixteen he stated and proved Pascal’s Theorem‚ a fact relating any six points on any conic section. The Theorem is sometimes called the "Cat’s Cradle" or the "Mystic Hexagram." Pascal followed up this result by showing that each of Apollonius’ famous theorems about conic sections was a corollary of the Mystic Hexagram; along with Gérard Desargues (1591-1661)‚ he was a key pioneer

frequency for something to happen. Blaise Pascal is referred to as the father of probability. Pascal contributed to the branch of mathematics known as probability in 1653. Through his work in probability‚ Pascal invented the binomial coefficients which are now known as Pascal’s Triangle. Pascal’s major input to the philosophy of mathematics came with his “Of the Geometric Spirit””.1 Blaise Pascal was also a major contributor to the founding of Statistics. Blaise Pascal contributed to mathematics in many

there must be a God or transcendent being that created the universe‚ as well as all of the nature within it due to the fact that it seems implausible for something so complex to have been created with no thought or planning. In chapter eight‚ Pascal writes‚ “…for nothing is certain‚ and that there is more certainty in religion than there is as to whether we may see to-morrow; for it is not certain that we may see to-morrow‚ and it is certainly possible that we may not see it.” I found this to

Pascal’s Wager does not provide has some challenges in its reasoning and is not a convincing argument for one to believe in God‚ but it can be applicable to a catered category of people. Pascal’s Wagers main issue is that it is not an epistemic argument. Before just dismissing Pascal’s Wager as not an epistemic argument‚ one must understand what an epistemic argument is. An epistemic argument is an argument that must be rational‚ reasonable and justified in order to be believed. For instance‚ if

Blaise Pascal was a French philosopher‚ mathematician‚ scientist‚ inventor‚ and theologian. In mathematics‚ he was an early pioneer in the fields of game theory and probability theory. In philosophy he was an early pioneer in existentialism. As a writer on theology and religion he was a defender of Christianity. Existentialism - a philosophical theory that emphasizes the existence of the individual person as a free and responsible agent determining their own development through acts of the will
